What Is a Situationship

You see each other most weeks, you may sleep together, and you can't ask what this is without changing it. A situationship is a romantic or sexual connection that has intimacy but no agreed label. You have no exclusivity agreement or shared plan for where it goes. So set their answer aside for a minute; the question you can answer on your own is what you want this to be.

What a situationship is

A situationship behaves like a couple in private and declines the word in public. Oxford University Press, which shortlisted the term for its 2023 Word of the Year, defined it as "a romantic or sexual relationship that is not considered to be formal or established." A 2025 paper by Langlais and colleagues in Sexuality & Culture put it more sharply: partners "act like an established romantic couple, but do not put a label on the relationship and avoid commitment."

Most situationships share a handful of traits:

No label: Neither of you has said "partner," "boyfriend," "girlfriend," or "we're together," and both of you keep the omission going rather than letting it happen accidentally.
No exclusivity agreement: You may or may not be seeing other people. You don't know for sure about them, because neither of you has settled the topic in either direction.
No future talk: Plans run a week or two out. The wedding with a plus-one in June stays unsaid. So do the trip you'd like to take and whether they'll meet your sister.
Couple-like behavior anyway: You text daily and sleep over. You also know each other's friends by name. In a 2026 study of 261 college students at one Southeastern US university, Langlais and Davidson coded 34.1% of the 468 relationship experiences the students described as situationships on exactly this basis. The sample was 82.3% women, mostly white, and from a single campus, so the figure describes those students rather than everyone.
Ambiguity that both people maintain: Knobloch and Solomon observed in a 2005 study of 120 couples that "people may prefer to maintain ambiguity over certainty regarding unpleasant outcomes." The vagueness does a job for at least one of you.

This is common. In a nationally representative YouGov poll of 1,110 US adults run January 24–25, 2024, 50% of those aged 18–34 said they had been in a situationship. The word itself spread on TikTok from late 2020, where BBC Worklife counted more than 839 million views on #situationship by September 2022. Merriam-Webster added a formal dictionary entry on February 24, 2026.

Are you in one? Three questions to ask yourself

You can place yourself without decoding a single text from them. The answers about the relationship are in your own behavior over the past month.

Status: If a coworker asked what you and this person are, what would you say? Now picture saying the same sentence with them standing beside you. If the two versions differ, the gap between them is the situationship.
Consistency: Do you know when you'll next see them without asking? Do you plan your week around them while they seem to fit you into theirs? One quiet week tells you little; the pattern across six or eight weeks tells you more.
Future: When did either of you last mention anything more than two weeks away? Would suggesting a trip in the spring feel like a presumption you'd need to walk back?

If you found yourself wanting to answer with several labels at once, that fits the data. In a 2020 dissertation study of 144 college students in ambiguous partnerships (not peer-reviewed, and drawn only from people already in undefined situations), 56% picked three or more labels for the same relationship. "Hanging out" led at 63%, followed by "hooking up" and "dating" at 42% each.

The questions above also tend to sit unasked for a reason that compounds. Knobloch and Theiss followed 135 dating couples with weekly diaries for six weeks and found that people who avoided relationship talk in one week reported more relational uncertainty the following week. The silence feeds the fog you hoped it would protect you from. Placing yourself here gives you clarity about the arrangement; it does not give you certainty about them, and those are different things.

Situationship vs. casual dating, FWB and a real relationship

These arrangements get confused because none of them carries a formal label; they differ in what the two of you have agreed and how you appear to other people:

Arrangement	Intimacy	Exclusivity	Future talk	Social integration
Situationship	Sexual and emotional; couple-like in private	Unsettled; never agreed either way	Avoided by at least one person	Partial; friends may know, family usually doesn't, no public label
Casual dating	Dates and often sex; emotional depth varies	Non-exclusive by understanding	Not expected	Low; you rarely meet each other's people
Friends with benefits	Sexual, added to an existing friendship	Typically non-exclusive	Rare; the friendship is the frame	Already integrated as friends, not as a pair
Booty call	Sexual only, on short notice	None	None	None
Talking stage	Emotional and digital; often before sex	Undefined and usually brief	Implied; the point is to become something	Minimal
Exclusive relationship	Sexual and emotional	Agreed out loud	Expected and ongoing	Full; introduced as a partner

Exclusivity is the column people most often assume rather than settle. When Muise, Belu and O'Sullivan asked 573 people about their exclusivity agreements, 43% had formed them through an explicit conversation and 52% described the agreement as implied and never discussed. If you are counting on an implied one, our guide to exclusivity in situationships covers how to tell an agreement from an assumption.

Casual versus serious is the other line worth its own page. Owen and Fincham surveyed 764 college students in exclusive relationships and found that 19.6% said their relationship began as friends with benefits; those relationships showed lower satisfaction even after controlling for attachment and alcohol use, though they were no more likely to end over the four-month follow-up. Casual arrangements can turn serious, and the ones that do carry their history with them. Our casual-versus-serious guide covers how to tell which one you're in.

Why people end up in situationships

Staying in a situationship is what several ordinary tendencies predict, and none of them is a character flaw. Each one below describes a pattern researchers have measured across many people. None of them describes you specifically, and you'd be right to hold any that sounds familiar loosely.

Attachment patterns

Hazan and Shaver's 1987 paper translated infant attachment research into adult romance using a newspaper sample of 620 people, and Brennan, Clark and Shaver later organized the field into two dimensions: anxiety, meaning worry about a partner's availability and your value to them, and avoidance, meaning discomfort with closeness and a preference for self-reliance. Everyone sits somewhere on both. Researchers have validated these self-report scales mostly on college samples, and a quiz result is a data point rather than a verdict.

Each dimension pulls toward the undefined middle from a different side. In a five-week daily diary, DeWall and colleagues found higher avoidance predicted a greater daily desire to meet alternatives (β = 0.11, a small effect), and lower commitment explained that link. In everyday terms, someone high in avoidance keeps the door open by never closing it. On the other side, Slotter and Finkel found that people high in attachment anxiety sustained dedication to unfulfilling relationships where low-anxiety people let commitment decline, and George, Hart and Rholes reported that fear of change and fear of being alone helped explain that link. If you notice you would rather have the undefined version of this person than none of them, that is the pattern being described.

The two tendencies also find each other. Kirkpatrick and Davis followed 354 dating couples for three years and found no anxious–anxious or avoidant–avoidant pairs; relationships between avoidant men and anxious women were "surprisingly stable over 3 years, particularly in light of the relatively poor ratings of these relationships by both partners at Time 1." An arrangement can feel bad and last a long time at once.

Fear of commitment

The APA Dictionary defines fear of commitment as "feelings of anxiety and uncertainty related to the decision to become bound to a course of action." It is a descriptive phrase rather than a diagnosis; "commitment-phobia" has no substantive APA entry, and the DSM-5-TR names no such condition. Practitioner writing often treats it as a situational cousin of avoidance, and the research does not draw a sharp line between them.

Circumstance plays a part too. Across five studies, Brady, Baker, Agnew and Hadden found people were less ready to commit the more romantic options they believed they had. A phone full of matches may lower readiness in either of you without anyone deciding anything.

Uncertainty and reward

Popular explainers say situationships run on "dopamine hits," and the honest version of that claim has layers. Schultz, Dayan and Montague showed in 1997 that primate dopamine neurons code the gap between expected and received reward. An unpredicted reward produces a spike. A fully expected one produces no change from baseline, while an omitted expected reward produces a dip. Aron and colleagues found in 17 people intensely in love that a photo of the beloved activated the same dopamine-rich regions. And Whitchurch, Wilson and Gilbert ran an experiment with 47 female undergraduates in which women left uncertain about how men had rated them were more attracted to those men than women told the men liked them a lot, and thought about them more.

That is where the evidence stops. No peer-reviewed study has tested whether hot-and-cold texting produces a dopamine reinforcement response in humans, and Hostetler and Ryabinin have cautioned against this framing as "addiction." The message that lands hardest when you'd stopped expecting it is consistent with what's known; the chain from pigeon experiments to your lock screen is inference.

Limerence

Dorothy Tennov coined limerence in her 1979 book after interviewing more than 300 people, and described it as a state of "involuntary obsession" with another person organized around "acute longing for reciprocation." Her central claim was that "limerence endures as long as do the conditions that sustain both hope and uncertainty." It appears in neither the DSM-5 nor the ICD-11, and a 2024 review calls the study of it "still in its infancy." Tennov estimated the typical episode at about two years, with most falling between 18 months and 3 years.

A situationship supplies exactly the hope-and-uncertainty mix she described. If your mood on a given day tracks their reply time, and if some part of you senses that a plain conversation would end the not-knowing and hesitates for that reason, you are noticing a pattern consistent with the mechanism she described. The research in this section may help explain why leaving can feel hard, but it cannot predict how any one person will respond.

What the ambiguity does to you

Tuesday they text "miss you" and your afternoon is light. By Thursday, you reread Tuesday to check it happened because there's been nothing since. That swing is the cost, and researchers studying relational uncertainty have measured related patterns in the general population with some precision:

Anxiety, depression and self-esteem: A prospective longitudinal analysis of 928 emerging adults from the Toledo Adolescent Relationships Study found relationship uncertainty was positively related to anxiety and depression. It was negatively related to self-esteem, with a stronger effect than financial uncertainty on all three. This is a working paper from Bowling Green's demographic research center, so treat it as strong but not yet peer-reviewed.
The pooled picture: Goodboy and colleagues ran 27 meta-analyses of the relational turbulence literature (9 to 15 studies each, sample sizes from 1,395 to 5,493) and found that uncertainty about yourself and your partner, plus uncertainty about the relationship, all correlated with depressive symptoms and lower satisfaction. Most of the underlying studies were cross-sectional, so they describe an association rather than a cause.
The swing itself: Researchers surveyed a panel of 748 unmarried adults aged 18–34 six times at four-month intervals. Greater fluctuation in relationship quality went with rising psychological distress and falling life satisfaction over time. The Tuesday-to-Thursday pattern is an everyday analogy, not the variable this study measured.

The arrow runs both ways. Knobloch and Knobloch-Fedders found in 85 couples that depressive symptoms also predicted relational uncertainty, so a low stretch can make an arrangement feel murkier than it is. On self-esteem, Leary's sociometer studies found that exclusion lowered self-esteem when people attributed the exclusion to themselves, and people's feelings about themselves tracked their sense of being excluded at r = −.75. The inference to situationships is mine: when someone fits you in around their schedule, that can register as a small, repeated exclusion.

You may have read that situationships "spike cortisol." The only study I could find linking relational uncertainty to cortisol is Priem and Solomon's 2011 work with 89 established dating partners, which found partner uncertainty went with greater cortisol reactivity to a hurtful interaction and also with less recovery after receiving support. No cortisol study covers undefined relationships, so the popular claim is an extrapolation. What you can trust without a lab is the drop in your stomach when their name doesn't appear.

Pauline Boss coined "ambiguous loss" in the 1970s while working with wives of pilots missing in Vietnam, and defines it as a "relational disorder caused by the lack of facts surrounding the loss of a loved one," marked by "no resolution." Her second type covers people who are physically present and psychologically unavailable. Boss has not named situationships as a category, and applying her framework here is a practitioner extrapolation; LeFebvre and Fan did extend it to ghosting in two empirical studies. If you have felt something like grief for a thing that hasn't ended, her concept explains why the feeling has no shape to hold onto.

The real question: what do you want this to be

What you want this to be is the only part of the situation you have full access to, and it's the part most people skip. You've screenshotted their last message to two friends. The group chat has three theories. Every one of them is about the other person.

Communication researchers have a name for what the decoding turns into. Baxter and Wilmot catalogued 14 kinds of "secret tests" people run instead of asking. Endurance tests add costs to see if the other person stays. Indirect suggestion tests include joking about the relationship or touching more, while public presentation tests include introducing someone as a partner to see how they react. In a companion study, they found that the state of the relationship was "the most pervasive" taboo topic, with people describing relationship talk as "destructive, inefficient, futile and risky." Each test produces a scrap of information about them and none about you.

So run the question inward first. If they brought it up tonight and said yes to everything, what would change in your Wednesday? If they said "I like this as it is," would you stay, and for how long? Is the thing you want this specific person, or a defined thing with someone, and this person happens to be here?

Knowing the answer is harder than it sounds, and separate from saying it. In Konstam and colleagues' interviews with 29 emerging adults, most could describe what a committed relationship would mean to them and still hesitated to tell their partner they wanted one. Hinge told Metro in 2021 that every user who reported turning a situationship into a relationship said they had first become clearer about what they wanted; Hinge did not publish its method, so hold that as a hint rather than a finding.

Clarity here is not certainty. You can be clear that you want exclusivity and have no idea whether you'll get it. The first is yours to settle. The second requires them, and it comes next.

When it can become a relationship, and when it cannot

A situationship becomes a relationship when both people say what they want and the answers match. The closest longitudinal data comes from friends-with-benefits arrangements, a related but distinct construct. Machia and colleagues followed 192 FWB relationships and found that among people who wanted the arrangement to become romantic, 15% got there, while 59% of those who wanted friendship got that. Only 30% of the whole sample ended up in the arrangement they had wanted at the start. The FWBRs that did turn romantic involved more communication about expectations and future commitment.

In Bisson and Levine's retrospective study, 10% of FWB arrangements evolved into romance, and 73% of participants said they had negotiated no ground rules at the outset. Langlais, writing in Psychology Today in 2024, described situationships as ones that "do not often evolve into committed romantic relationships," a directional claim without a published rate.

Stanley, Rhoades and Markman's sliding-versus-deciding framework explains part of why. Couples who drift into milestones accumulate constraints: "Increased constraints may make it more difficult to terminate the relationship, but the partners may or may not feel more dedicated." The spare key and the toothbrush at their place are constraints. Dedication is a different thing, and in a sample of 252 adults (median age 28), the people who reported more deliberate decision-making about their relationships also reported more of it, along with higher satisfaction. Mismatched dedication has its own numbers: in a national sample of 315 couples, breakup rates within two years ran 54% when the woman was less committed and 29% when the man was. The rate was 34% when commitment was matched.

The conditions that let a situationship become something agreed are recognizable when you see them.

Terms said out loud: Both of you have stated what this is, even if the statement is "casual for now," and neither of you is privately translating it into something else.

Check-ins that can change the answer: You can raise the topic again in two months without it counting as an ambush, and either of you can report that something has shifted.

No hidden hope: You'd be at peace if this stayed exactly as it is for another year. If that sentence made something tighten, the hope is doing more work than the arrangement can carry.

A situationship that meets those conditions is an agreement, and some people choose it. In Tinder's 2022 in-app survey of 18-to-24-year-olds in the UK, US and Australia, more than 1 in 10 said they preferred situationships as a lower-pressure way to let things develop. That's an app-user sample, so it describes Tinder users rather than young adults in general, but it confirms that both people can want the arrangement.

The case for walking looks different. You want a thing they have told you they don't want, and staying is a bet on them changing. How long have you been placing that bet, and what has changed since you started?

How to have the conversation

The moment to ask is when the not-knowing has started to shape your decisions. Psychologist Easton Gaines put it this way in Verywell Mind: "The right time is typically when uncertainty outweighs clarity: when you find yourself wondering about where things stand or making decisions (big or small) that would be influenced by the answer." If you've turned down a date, kept a weekend open, or skipped a plus-one because of this person, you're there.

Researchers have not tested any of the scripts below in an experiment; practitioners offer these framings, and you can adapt the plain language. The following approaches vary in how exposed they feel:

Curiosity first: Verywell Mind's suggested framing is "I've been thinking about where we're headed. What are your thoughts?" rather than "We need to define this now."
Name the awkwardness: Psychologist Sabrina Romanoff, in Verywell Mind, offers: "I feel a bit awkward and vulnerable about this, but I want to be honest and would like to have a talk about where we stand." Her rule of thumb is to speak first about your own feelings and needs without pressing for a response.
State your position, release the timeline: "I've realized I want us to be exclusive. I don't need an answer tonight, but I wanted you to know where I am." This works only if you've done the previous section and mean it.

Expect common deflections, and decide in advance how you'll answer.

"I'm not into labels." Try: "That's fair. I care less about the word than about whether we're both only seeing each other. Are you?" You've moved the question from vocabulary to behavior, which is harder to deflect.

"Let's see where it goes." Try: "I've been seeing where it goes since March. Where would you like it to go?" If the answer is "I don't know," ask what would need to be true for them to know.

"I'm not ready." Try: "Not ready for what, specifically? And is that about timing, or about us?" Their answer tells you whether you're waiting for a date or for a different person.

Whatever they say, know what you're doing next. The Gottman Institute distinguishes a request from a boundary. A request asks for a change, with the outcome out of your control. A boundary sets a limit on your own behavior and matters only if you keep it. An ultimatum, by contrast, is "specifically designed to control somebody else." "I'd like us to be exclusive" is a request. "I'm not going to keep sleeping with someone who's seeing other people" is a boundary. "Decide by Friday or we're done" is an ultimatum, and it only makes sense if you would follow through.

The conversation can help. In Knopp, Rhoades, Stanley and Markman's study of 341 young adults, define-the-relationship talks had happened in over half of participants' most recent relationships and often "resulted in positive changes in the relationship, including increased clarity, intimacy, and commitment." Theiss and Solomon found across six weeks of couple diaries that a drop in uncertainty was the only significant predictor of increased intimacy the following week. They also cautioned that total openness is not always beneficial under uncertainty. For more on wording, timing, and what to do when the conversation goes sideways, see our guide to defining the relationship in the Difficult Conversations & Conflict section.

If the answer is to leave

End it in words, even though no rule says you have to. In three preregistered studies, Leckfor and colleagues worked with samples of 553 and 411 participants; the third included 545. People who recalled someone ghosting them reported lower needs satisfaction than people who recalled someone directly rejecting them, partly because ghosting "does not clearly indicate to the target that the relationship has ended." Timmermans and colleagues found in 328 people that how unexpected a ghosting felt was a significant predictor of how painful it was. Something like "I've realized I want a relationship, and this isn't heading there for you. I'd rather say that than fade out" takes thirty seconds and spares both of you the slow version.

The slow version has its own cost. Navarro and colleagues found among 626 Spanish adults that breadcrumbing, meaning occasional "we should hang out sometime" contact after an implied end, went with lower life satisfaction and more helplessness and loneliness, while ghosting alone showed no such link in that sample.

Then let yourself grieve something that had no name. In Anderson and Phillips's participant interviews with 14 Australians aged 19 to 25, participants called situationship endings "soul-crushing" and described distress that "did not count because situationships were not 'real relationships.'" One put it this way: "when it ends, I feel like you can't even be heartbroken cause you weren't 'in a relationship.'" Kenneth Doka's term for this is disenfranchised grief, "the grief that persons experience when they incur a loss that is not or cannot be openly acknowledged, publicly mourned, or socially supported."

No study has directly compared how hard defined and undefined relationship losses land. The available evidence suggests that a missing label does not necessarily make the loss slight. Rhoades and colleagues followed 1,295 unmarried adults for 20 months and found no relationship or breakup characteristics significantly moderated changes in psychological distress after a split. What did predict distress in Slotter, Gardner and Finkel's self-concept studies was a loss of self-concept clarity: the person had become part of how you understood yourself, label or not.

Choose who you tell with that in mind. Robak and Weitzman found in 126 college students that parents and siblings disenfranchised grief after romantic loss, but friends did not. The friend who watched you check your phone for four months will probably understand. A parent who never heard the person's name may not.

Shared circles need a plan rather than a rule. Decide the one sentence you'll say when someone asks: "We stopped seeing each other. It's fine." Then decide whether you're going to the birthday thing this month. Before a run-in happens, decide what you want it to do for you. Sbarra and Emery tracked 58 undergraduates for 28 days after breakups and found contact with the former partner slowed the decline in both love and sadness. That is a finding about averages, not an instruction; it leaves you with the question of what each contact is for. Our Breakup section covers the weeks after this in more detail.

Work out what you want before the conversation

The conversation two sections up goes better when you've already answered the questions in "The real question" section, and most people rehearse that step in a group chat that has opinions. Mutually is a rehearsal room for it. You start as a guest without providing an email or name, and you provide no payment information. The system automatically creates a random guest identifier for you. You type what's happening, and Mutually replies with reflective questions, along the lines of what you'd want them to say if they texted right now, or what would change for you if the answer were no. You can pick from suggested responses or write your own. Each session ends with a summary and takeaways, and you can delete any conversation. If you verify an email, your sessions carry across devices so you can check whether your answer in week two matches your answer in week six.

The first session is free, and the paid plan is $9.99 per month or $59.99 billed annually after that. Mutually is AI-guided. Not therapy. It doesn't put a label on you or take sides against the other person. It doesn't decide what you should do; it asks the questions until you can hear your own answer. If you want to think through your own situation, start a free session with Mutually. Say what happened, then follow the questions wherever they lead.

FAQ

Four questions come up more than any others about situationships, and the honest answers include some gaps in the research.

How long does a situationship last?

No rigorous study has measured an average situationship duration; peer-reviewed work on the topic is mostly cross-sectional, and app companies have not published duration figures. The nearest proxies come from friends-with-benefits research, where Machia's team saw 31% of arrangements dissolve into no relationship at all and 26% continue unchanged over their follow-up, and from Tennov's estimate that infatuation sustained by uncertainty typically runs two years. Neither number is a rule for your situation. A more useful measure is Gaines's: the arrangement has lasted long enough when the uncertainty starts shaping decisions you'd make differently with an answer.

Should you say "I love you" in a situationship?

Say it if it's true and if you can name what you want the words to do. Before you do, ask yourself which response you're hoping for and what you'll do if you get a different one. If the answer is that you'd stay regardless, you're offering information. If the answer is that you'd need to leave, you're asking a question with three words, and you may want to ask it in a way they can answer. Either is legitimate; knowing which one you're doing protects you from hearing "thank you" as a verdict.

Can a situationship turn into a real relationship?

Yes, and the ones that do are the ones where both people talked about what they wanted. In the FWB data closest to situationships, 15% of people who wanted romance got there, and the FWBRs that transitioned involved more discussion of expectations and future commitment than the FWBRs that didn't. Relationships that begin without a label can also carry that start with them: college students whose exclusive relationships began as friends with benefits reported lower satisfaction than those whose didn't. Neither finding predicts your outcome. Both suggest that the shift happens through a conversation rather than around one.

Why does it hurt so much to leave something that wasn't official?

Researchers have not directly compared grief intensity after defined and undefined relationships. Indirect evidence helps explain why an undefined loss can still hurt: in a 20-month study of nearly 1,300 unmarried adults, formal relationship characteristics didn't moderate how distress changed after a breakup. Other work found the sharpest predictor of pain was how much the other person had become part of your sense of yourself. Add a social circle that thinks you weren't in anything, and you may have grief without permission to feel it. The pain does not prove what the relationship was. It does show that the connection and its loss mattered to you, whatever you called it.
