Crush on Someone Who's Taken? Your Real Options
Entry No. 114 ·
By The IF Team
Having a crush on someone who is taken is not wrong, and it is not rare. Attraction does not check anyone’s relationship status before it arrives, and feeling it says nothing bad about you. It is simply honest. What matters is what you do with it, and you have more options than the films suggest: hold the feeling quietly, turn the volume down for a while, keep the friendship with clearer edges, tell them how you feel, or say it now in a sealed message that waits until the timing is right for both of you.
The one thing that is not an option is going behind anyone’s back. Cheating hurts people, and so does lying. Everything in this guide sits on the honest side of that line, and so does IF, the dating app we built for feelings like yours: no conversation can open on IF while either person is marked as in a relationship, but you can still say what you feel.
Is it wrong to like someone in a relationship?
No. A feeling is not a decision, and you cannot reason your way out of one. You can like someone who has a girlfriend, fancy someone who is taken or feel a real pull towards a friend who is married, and still be a good and decent person. Feelings that cross relationship lines are part of being an adult with a full heart, and admitting them, to yourself and to the people who matter, is emotionally honest rather than shameful. If you are the one in a relationship, the questions are a little different, and having a crush while you are in a relationship is the guide for you.
Where it does matter is in what you do. A crush stays honest when it stays in the open. It stops being honest when it turns into things you would need to hide:
- Secret meetings, or late-night conversations you would not want anyone to see.
- Flirting designed to test whether they would stray.
- Running down their partner, or hinting that you would treat them better.
- Lying, to them, to their partner or to yourself, about what is going on.
None of that is needed to honour how you feel. If you notice yourself drifting towards one, it is not a reason for shame. It is a signal to bring the feeling back into the open, where it belongs.
Why the taken ones feel so magnetic
Part of the pull is almost mechanical. A partner works like a reference: someone has already looked closely at this person and said yes. Psychologists call the effect mate-choice copying, and in one well-known experiment some single participants showed more interest in pursuing a potential match when told that person was already in a relationship than when the same profile was described as single.
Part of it is ease, because there is no pressure when nothing is on the table. And part of it is simply time: the colleague who always saves you a seat, the friend who remembers how you take your coffee, the person you met when they already had a partner and liked anyway. If it keeps happening, why we fall for people who are taken looks at the pattern with curiosity rather than blame.
Your real options
Most advice offers two choices: say nothing forever, or confess and see what happens. The real range is wider, and the right option depends on how close you are, how strong the feeling is and how much of your life it is taking up.
Name it to yourself
The simplest option is also the most underrated. Name the feeling — “I have a crush on them, and they are with someone” — and let it be true without building a plan around it. Tell a friend, write it down, say it out loud on a long walk. Feelings that are acknowledged tend to settle. Feelings that are hidden, even from yourself, tend to grow in the dark.
Turn the volume down for a while
If the feeling is loud, a little space helps you think. It can be as small as skipping the last drink once everyone else has gone home, answering the late message in the morning or muting their stories for a few weeks. You do not owe anyone an explanation, and you do not have to cut them out. You are simply giving yourself room.
Stay close, with clear edges
If the friendship is real, keep it. Spend time together in groups as well as one to one, and get to know their partner as a person rather than an obstacle. Notice, too, if you are becoming their main confidant about problems at home, because that role can blur lines quickly for both of you.
Tell them
You can tell them. Emotional honesty is brave, and some people would rather know. But be clear-eyed about the risks of opening up face to face: it puts them on the spot inside a relationship they have chosen, it can make a friendship awkward overnight, and it cannot be taken back. If you do, keep it to one honest sentence that asks for nothing, and if they ask for space, give it. We weigh the moments when saying it out loud is worth it in telling someone who is taken that you like them.
Say it in an IF, and let it wait
There is a middle path between silence and a confession. An IF lets you say exactly how you feel, now, in a private, sealed message that opens only if you are both single one day. It is sealed, not secret: nothing about it needs hiding or a lie. It asks nothing of them today, and no conversation can open between you while they are with someone. And if the timing ever lines up, you are already there, with proof of how long you have felt this way. That is what IF is for.
If your crush has a boyfriend, girlfriend, fiancé or spouse
The label changes the stakes. It does not change the honesty of what you feel.
My crush has a boyfriend (or a girlfriend)
A dating relationship can look provisional from the outside, especially a new one, but it is theirs to run, and the respectful move is to let it run its course without a push from you. Some relationships last and some do not. If yours is the feeling that outlasts theirs, an IF means you can show them it was there all along.
My crush is engaged
The months before a wedding are when many people feel the urge to say something “before it is too late”. A confession then lands on top of everything else they are carrying, so think hard before you make one. Writing it in an IF lets you say it without asking them to decide anything, and being in love with someone who is getting married walks through those months in more detail.
My crush is married
Marriage usually means more at stake: a shared home, sometimes children, two families. Your feelings are no less real for that, and you do not have to pretend they are not there. An IF lets you say it without touching anything they have built: it stays sealed unless you are both single one day, and then you can show them you felt it all along. If you are already more involved than a crush, our guide to being in love with a married man or woman is written for exactly that. And if you have only just found out that the person you are seeing is married, start with what to do when you find out they are married.
The setting matters too. Feelings for your best friend’s boyfriend or girlfriend involve a friendship as well as a relationship. A crush on a coworker who is taken follows you into work every day. A crush on a sibling’s partner sits inside your family. Each has its own guide.
Jealous of your crush’s partner?
Jealousy here is normal, and it does not make you a bad person. You can wish someone well and still feel a small, sour drop in your stomach when they post a photo with their partner. Both things are true at once.
It helps to remember that their partner is not your rival or the villain of your story. They are a person with their own history, doing nothing wrong by being loved. Casting them as the obstacle only hardens the feeling into resentment, and resentment is the quickest way for something tender to turn sour.
It also helps to stop feeding it. Research on people getting over an ex found that checking the ex’s Facebook page was linked to more distress, more longing and less personal growth. Scrolling through your crush’s couple photos is unlikely to work any differently. Mute them for a season, and notice how much quieter your head gets.
Then ask what the jealousy is pointing at. Sometimes it is the person. Sometimes it is what they have: being chosen, being someone’s first call. Both are worth knowing: the first tells you who you want, and the second tells you what you are ready for.
When they seem to like you too
Sometimes the hardest version is not a quiet crush but a connection that seems to run both ways: long conversations, private jokes, the sense that they understand you. That is real, and it is worth taking seriously. If you are still trying to read what their attention means, our guide to the signs someone in a relationship likes you will help, and if they have already said it out loud, what to do when someone taken says they like you picks up from there.
Research on adults in exclusive relationships finds that crushes on people outside the relationship are common. Sometimes the feeling runs both ways, and a spark between you does not mean anyone has done anything wrong. What keeps it honest is keeping it in the open: no secret meetings, no messages that would need deleting, nothing that asks either of you to lie.
Whether they stay in their relationship is their decision, made in their own time. If they ever find themselves single while you are too, your IF lets you show them you felt it all along, and said it honestly.
When the feeling will not fade
For most people, a crush on someone in a relationship softens with time and a full life. For some, it does not. If you find yourself checking their social media several times a day, planning your routine around the chance of seeing them or struggling to concentrate on much else, the feeling may have tipped into something heavier. Some people call this limerence, and it is not a character flaw. However, if it has reached the point of turning up where they will be, or messaging after they have asked for space, stop there and talk to someone; you do not have to manage it alone.
And if you decide you would rather move on, that is a valid choice too, and it does not have to mean leaving it unsaid: you can send an IF, set the feeling down and get on with things, knowing it is there if the timing ever changes. Our guide to getting over someone you cannot be with walks through it step by step.
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 it like any dating app: a Like, once accepted, opens a chat. When either of you is taken, no chat can open, but you can still send an IF: a private, sealed message of up to 250 characters that waits for the right moment.
If you are single and your crush is in a relationship, your IF stays sealed for as long as they are with someone. If they become single while you are still single, you get 24 hours to reveal it. If you do, they see who you are and what you wrote, and choose whether to accept, and accepting opens a chat with your IF as its first message. And if you are in a relationship yourself, you can still send one: it simply waits until you are both single. How an IF works covers every situation in detail.
It is worth knowing how it lands. If they are on IF, they will usually be told that an IF is waiting for them — never who sent it or what it says. If they are not on IF yet, one sent to an email address they gave you triggers one short invitation email, without your name or your words, while one sent to a phone number or Instagram handle simply waits in case they join. IF never discloses who sent it before a reveal. However, they can still guess from context. Knowing that, the choice is yours.
Your first IF is free, and how to send the perfect IF will help you find the words. Writing one takes a little courage, and that is rather the point: you say it once, mean every word, and then it does the waiting while you get on with your life. If the timing ever lines up, it may lead you to where you were meant to be all along.
Questions people ask
Is it normal to have a crush on someone who is taken?
Yes. Crushes grow around the people you see often and feel at ease with, and plenty of those people happen to be spoken for. Having one is human, and admitting it is honest.
Should I tell my crush I like them if they have a boyfriend or girlfriend?
You can, and some people are glad they did. Saying it face to face carries real risks, though: it puts them on the spot and can unsettle a friendship overnight. You may be better off sending a sealed IF, because it says everything and asks for nothing until you are both single, and if the timing ever lines up, you are already there.
Should I wait for my crush to become single?
If they feel like the right person and the timing is wrong, waiting is not foolish. It is hope. The simplest way to wait is to say it once, in an IF, and keep living your life, so that if their situation ever changes, you can show them how you felt all along. Whether to wait for someone who is taken looks at it in more depth.
How do I stop liking someone who is taken?
You cannot switch a feeling off, and you have nothing to be ashamed of. What helps is giving it less to feed on and more of your own life to compete with: your friends, your plans, the things you loved before they arrived. Writing it down in an IF can be what finally lets it rest, because it has been said and no longer needs rehearsing in your head. If it keeps circling back, why you cannot stop thinking about someone explains what is going on.
How long does a crush on someone taken last?
There is no fixed timeline. Crushes fed by daily contact and constant checking tend to last longest, while time, a little distance and a full life usually soften them, though some quietly last for years. If months pass and it still shapes your days, talking to someone can help.
