Signs Someone in a Relationship Likes You (and What It Means)

Entry No. 091 ·

A packed fraternity house party at night, lit only by string lights and one low lamp, deep shadows, dozens of college students of about twenty to twenty-two crowded shoulder to shoulder in jeans, plain unbranded hoodies and plain tees, plain plastic party cups in hand, no lettering anywhere. Near the stairs, a young woman laughing with two friends holds a deep rose pink cup and catches the eye of a guy across the room, who smiles back openly from the middle of a laughing group that includes his girlfriend; everyone is chatting together, and the mood is warm and quietly hopeful.

By The IF Team

The clearest signs that a taken man or woman likes you come as a pattern, not a single moment: they find reasons to be alone with you, message you when their partner is not around, flirt and then pull back, mention their partner rarely or only to complain, and bristle when you talk about dating. What those signs mean is narrower than it feels, but it is not nothing. They show interest, not yet a decision: a real pull they may not have worked out themselves. What happens to their relationship is theirs to decide, in their own time, and one day it might leave room for you. If it does, an IF means you will already be there.

It rarely feels that tidy from the inside. It is the colleague who always saves you the seat beside him, or the friend of a friend whose messages arrive after eleven, once his girlfriend has gone to bed. You replay a look, a joke, a “we should get a drink sometime”, and wonder whether you are imagining it. You are not foolish for wondering, and feeling it too is not wrong. If they have already said it out loud, what to do when someone taken says they like you picks up from there. This guide is for the hints, and for one option most guides miss: IF, the dating app where no conversation can open while either of you is in a relationship, but a sealed message can wait until you are both single.

Ten signs a taken man or woman likes you

No single sign proves anything. Some people are warm with everyone, and a kind colleague is not a secret admirer. What counts is a pattern that holds over weeks and keeps drifting towards time with just you.

  1. They make time for you alone. The offer of a lift, the coffee that becomes lunch. Time is scarce when you share a life with someone, so notice where theirs is going.
  2. Their messages arrive when their partner is elsewhere: late at night, on the evenings his girlfriend is out, during the week her husband is away.
  3. Their partner goes missing from the conversation. “We” quietly becomes “I”. You know about their commute and their childhood, and almost nothing about the person they live with.
  4. They complain about their partner to you. The row about the washing-up, the girlfriend who “doesn’t get him”. More on this below.
  5. They flirt, then retreat. A compliment that lingers, followed by a joke that takes it back. Hot and cold is often the sound of someone who likes you and does not yet know what to do about it.
  6. They remember everything. Your sister’s name, the interview you were nervous about, the song you mentioned once. That kind of attention can mean you are on their mind when you are not there.
  7. They react to your dating life. Too many questions about the person you went out with, a flicker of irritation, a dig dressed up as concern. Friends tend to be glad when your date went well.
  8. They talk in hypotheticals. “If I were single…”, “in another life”, “if we’d met first”. A hypothetical lets someone say the thing without acting on it.
  9. Their body language leans in. They face you across the table, find small reasons to touch your arm, hold eye contact a beat too long. On its own it proves little; alongside the rest, it adds up.
  10. It would all feel different if their partner walked in. This is the sign that matters most. If the tone would shift and the lunches would feel like something to explain, the feeling is probably real on their side too, even if neither of you has named it.

Interest, not yet a decision

Even when the signs are real, hold them lightly. They might point to feelings not yet worked out, a relationship quietly winding down, or simply a warmth they enjoy, and from the outside only time tells them apart. The decision about their relationship belongs to them, and you do not have to push for it or rule anything out: crushes sometimes become something real once the timing lines up, and an IF lets you say your part now, so that it is waiting if that day comes.

He has a girlfriend but flirts with me

It is tempting to take it as a compliment, and it is one: he finds you attractive. Flirting is not cheating, and a crush does not make him a bad person; good people get crushes. The same holds whichever way round it is: she has a boyfriend, he has a husband, they are engaged.

The line, for him and for you, is honesty: cheating is wrong and so is lying, whoever starts it. Open, easy warmth is neither. If you like him too, you do not have to choose between pretending you feel nothing and becoming anyone’s secret. You can tell him, but opening up face to face has risks. You are potentially better off sending an IF: no conversation can open on IF while either of you is in a relationship, and it stays sealed until you are both single, so that if the timing ever lines up, you are there to show him how much you have always liked him.

He has a girlfriend but keeps texting me

Texting is where most of this lives, because it is private, constant and deniable (“we’re just mates”). Notice when the messages come, and whether the thread would pass a simple test: would he be comfortable if his girlfriend read it over his shoulder? If yes, it may simply be a close friendship with a spark in it. If no, it has drifted somewhere that would need hiding, and if you feel it too, an IF is a steadier home for that feeling: write it down once, sealed until you are both single, and let the texts go back to being easy.

And if the messages are unwanted and keep coming after you have asked him to stop, they are no longer a mixed signal. Stop replying, block him, and see what to do when someone won’t take no for an answer.

Is a taken guy breadcrumbing me?

Breadcrumbing means offering just enough attention to keep someone interested without offering more: the “thinking of you” at midnight, the voice note after three quiet days, the plan that never quite happens. From someone in a relationship, it can feel as if you are being kept in reserve, which some people call cushioning, though it is just as often a feeling with nowhere else to go yet. Researchers call that person a back burner, and one study found that people in committed relationships reported as many back burners as single people did.

The rhythm can be a clue (warmth when you pull away, distance when you lean in), but from the outside it fits either reading. What you can choose is where your side of it lives. Put it in an IF, and let your own life fill the gaps: if the feeling is real on both sides, your IF can be waiting when the timing is right.

When he complains about his girlfriend to you

Of all the signs, this is the one that feels most like intimacy. He tells you things he tells no one else. His girlfriend does not listen; you do. People confide where they feel safe, and being the one he trusts says something real about the two of you. You are hearing one side, from someone who is hurting, and the closeness is real, which is exactly why it belongs in the open.

He says he’s unhappy in his relationship

Maybe he is. People do stay in relationships that are not working, and some say so to a friend first. Sometimes those relationships end, and sometimes the friend who listened turns out to matter most. None of it needs a nudge from you.

You can be kind without carrying the weight: “That sounds hard, and I think it’s one to talk through with her.” If you feel something too, an IF lets you say it without pushing, so that if he ever does find himself single, you are already there.

Signs a married woman (or man) likes you

The ten signs hold for someone married, and marriage adds a few of its own. Their children come up often and their husband or wife hardly at all. The messages fall silent through family holidays, then pick up the day they end. Marriage also has its own way of saying it: “we’re more like flatmates”, “we’re only together for the kids”, “it’s been over for years”. Often those words are honest, and either way the decision is theirs to make, in the open — and if it ever leaves them single, an IF means you are already there.

More is at stake, but your feelings are no less real for it, and an IF lets you say them honestly without asking anything of them now: no conversation can open on IF while either of you is in a relationship, and it stays sealed until you are both single. They may be told an IF is waiting, never who sent it or what it says. If what you feel has grown past curiosity, loving a married man or woman is its own conversation.

When the signs come from your boss

Attention from a partnered manager needs more care, because power over your work can make a late message or a push for drinks alone feel like pressure, whatever they intend. If it is unwanted, write down what happened and when, and speak to HR or someone senior you trust.

If the feelings are yours too, an IF lets you say so without putting either of you in an awkward spot at work: it stays sealed until you are both single. People can still guess from context, and work brings its own risks, so weigh that, then decide. A crush on a colleague who is taken covers protecting your job and your peace.

What to do with what you have noticed

You do not have to do anything with it. But if you feel it too, you have more options than silence or a confession:

  • Tell them, if you are sure. Emotional honesty is brave, but saying it face to face puts them on the spot and cannot be taken back.
  • Send an IF. You are potentially better off with a sealed message that waits, so that if the timing ever lines up, you are there to show them how much you have always liked them. Your real options with a crush on someone who is taken sets out the rest.
  • Wait, if they feel like the right person. Waiting is not foolish: say it once in an IF and keep living your life.
  • If you cannot stop replaying every look and message, talk to someone you trust.

Where IF fits

IF is a dating app for everyone, single or in a relationship, built around one idea: you should be able to say how you feel, whatever the timing.

Two single people use IF like any dating app: a Like, once accepted, opens a chat. When either of you is in a relationship, no Like, match or chat is possible, but you can send an IF: a private, sealed message of up to 250 characters that opens only once you are both single. If you are single and they become single, you get 24 hours to reveal it; if you are the one in a relationship and they are single, it reveals when you change your own status to single. Once it reveals, they see who you are and what you wrote, and choose to accept or decline; accepting opens a chat with your IF as its first message. How an IF works covers every situation.

It works both ways: if they feel it as well, they can send you one, and it waits for the same moment — the day you are both single.

If they are on IF, they may be told an IF is waiting, never who sent it or what it says, and they can delete it. If they are not, one sent to an email address they gave you triggers one short invitation email, while one sent to a phone number or Instagram handle they shared with you simply waits in case they join. People can still guess from context. Knowing that, the choice is yours.

Your first IF is free, and sending one is a relief: one message that means exactly what it says, left to wait while your own life carries on. If the timing ever lines up, it may lead you to where you were meant to be all along.

Questions people ask

Can a man in a relationship have feelings for someone else?

Yes. Attraction does not check anyone’s relationship status first, and research on people in exclusive relationships finds that crushes are common and that few people act on them. Feeling it is human. What matters is that he stays honest about it, and you do too. If he feels something for you and you feel it too, an IF lets either of you say so and let it wait for the timing.

How can you tell if a taken man is just being friendly?

Friendliness happens in the open. A friendly man is the same with you whether or not his girlfriend is in the room, and mentions her easily. Interest narrows: it seeks you out alone, moves to private messages and would change its tone if she walked in.

Should I say something if a taken man flirts with me?

That depends on how you feel. If it is unwanted, reply less, later and in company, or say it once, plainly: “I like being friends, but this feels like more, and I’m not comfortable with it.” If it carries on after that, it has stopped being flirting.

If you like him too, you can tell him, though opening up face to face has real risks. A sealed IF says it without asking anything of him until you are both single.

Will he leave his girlfriend for me?

No sign can tell you, and nobody can promise it either way. People leave when they have decided to, and sometimes the person who felt it all along turns out to be the right one. If you want to be there if that day comes, an IF lets you say so now and leave it waiting.

Their signals are theirs to send; an IF is yours. Right person, wrong time? Wait for them on IF.
