Crush on a Coworker Who's in a Relationship? What to Do
Entry No. 109 ·
By The IF Team
A crush on a coworker who has a girlfriend, boyfriend, husband or wife is common, and it does not make you a bad person. It is an honest feeling, and nothing to be ashamed of. What to do is simpler than it feels: keep it to yourself, stay warm and professional, quietly cut the one-on-one time that feeds it, and turn down the role of confidant. Confessing across the desk would risk your job and their relationship, but keeping it to yourself at work does not mean leaving it unsaid: an IF holds it in a sealed message that waits until you are both single.
What makes this harder than an ordinary crush is Monday morning. You cannot mute a colleague the way you can mute an ex. You share the same meetings, kitchen and managers, so every choice has three things riding on it: your job, their relationship and your own daily peace. This guide protects all three, and it holds one line throughout: cheating is wrong, and so is lying. Everything short of that is your call. For the wider picture beyond the office, start with your real options when your crush is taken.
Why work is where it happens
If you are wondering how you ended up here, the honest answer is proximity. In a 2020 survey by SHRM, the American HR professionals’ association, 54 per cent of American workers said they had had a crush on a coworker. In one set of experiments, pairs of strangers who talked for longer liked each other more, partly because they felt more understood and more at ease. Work runs that experiment on you every day, for years.
Work also shows you a flattering edit of a person. You see them calm under a deadline, generous in a meeting, remembering how you take your tea. You do not see them at home, tired and short-tempered about the washing-up. Add shared stress and in-jokes, and a crush almost builds itself. None of that makes it any less real. It makes you human, and it means you spend a lot of hours in one building.
Turn down the volume, not the warmth
You do not need to go cold on them. Sudden frostiness is as noticeable as flirting. The aim is ordinary friendliness with the charge taken out. A simple test for any moment with them: would you be comfortable if their partner, your manager and your closest friend all saw it? If not, that is the part to let go.
- Keep one-on-one time for work: meetings with an agenda, not long lunches for two or drinks after everyone else has gone home.
- Keep work chat about work. Let the late-evening messages and the private side-thread jokes go quiet.
- Stop volunteering for everything they are on. If a project would put you side by side for months, it is fine to let someone else take it.
- Mute them on social media for a season. You see enough of them at work.
- Do not dig into their relationship, through colleagues or through staff records. What they have not told you is not yours to find.
Decline the role of confidant
If they start telling you about problems at home, you do not have to be the person they tell. They are doing nothing wrong by confiding, but “I’m probably not the right person for this one” is kind, honest and, at work, wise. Becoming the colleague who understands them better than their partner does is how a crush turns into something neither of you meant.
Meet their partner as a person
If their partner comes to the summer party, say hello properly. It is much harder to romanticise a relationship once you have watched two real people share a bowl of chips and bicker about the last train home.
Give your evenings back to your own life
Not as a distraction, and not to make anyone jealous. Friends, the class you keep meaning to take and the weekends you keep promising yourself all shrink the part of your life that happens at one desk. Once you have said it in an IF, that is easier still: the feeling is waiting somewhere safe.
Why a confession at work is the riskiest way to say it
You can tell them, and emotional honesty is brave. But at work the risks are bigger than anywhere else. A confession asks a taken colleague to manage your feelings inside a relationship they have chosen, then sit across from you at Tuesday’s team meeting. It cannot be unsaid, and at work it can land as pressure, whatever you intended. We weigh the rare moments when saying it out loud is worth it in whether to tell someone who is taken that you like them.
With a colleague, there is a better way to be brave. An IF says exactly how you feel in a private, sealed message that opens only if you are both single one day. It asks nothing of them at work, and if the timing ever lines up, you are already there, ready to show them how much you have always liked them.
When the chemistry feels mutual
“He has a girlfriend, but we have chemistry.” “She has a boyfriend, but there is obviously something there.” It may be true. Work can also manufacture chemistry: shared deadlines, a common enemy in the monthly report. And banter is not a proposal.
If a colleague who is taken really does seem to be flirting — lingering after meetings, messaging late, confiding that things at home are not great — it may mean something, and it may not. It does not make them a bad person, or the spark between you wrong. Whether they stay in their relationship is their decision, made in their own time. Meanwhile, keep it honest: no drinks you would not mention, no messages you would want to delete. Crossing that line at work is still cheating: it puts their relationship and at least two jobs at risk, and teams usually notice long before anyone says a word.
If you want to act on the chemistry, an IF is the honest version. No Like, match or chat can happen on IF while either of you is in a relationship, so it can never turn into a secret relationship. It simply waits, and if you are ever both single, you can show them the chemistry was real all along.
Feelings for a married coworker
Marriage raises the stakes rather than changing the rules: a shared home, often children, two families, and far more people who would be hurt. It also tends to come with a longer story: years side by side, a hard season you watched them through, and one day the realisation that this is no longer a crush. If you are in love with your married coworker, that is painful and real, and nothing to be ashamed of. It is simply not something to act on behind anyone’s back.
Hold the same lines, more firmly: no confession across the desk, no private channel, no after-work meetings that would read differently if their spouse walked in. An IF says it without asking anything of them now: it stays sealed while either of you is in a relationship, and no conversation can open until you are both single. If the feeling is swallowing your working day, a change of team, or even of job, is not running away. It is choosing your peace, and an IF you have already sent keeps waiting, wherever either of you works. If things have already gone further than a crush, our guide to being in love with a married man or woman is written for that reckoning.
And if you are in a relationship yourself, you can still say it in an IF — it simply waits until you are both single — and work crushes when you are taken yourself covers the rest.
When one of you manages the other
A reporting line changes the stakes. A review of the research on workplace romance argues that power is the key to understanding when these relationships do harm, and the CIPD, the UK’s professional body for HR, notes that the risks can be greater when a relationship is between a manager and a more junior member of staff. Even mutual feelings are not felt on equal terms when one person shapes the other’s pay, projects and prospects.
It is worth reading your employer’s policy on relationships at work, too. Many ask staff to disclose a relationship within a reporting line, and some forbid one outright. A crush needs no disclosure, but knowing the rules shows you where the line sits.
A crush on your boss who is married
Crushes on a boss are often tangled up with admiration, gratitude and the wish to be noticed by someone whose opinion shapes your future. That does not make the feeling fake, but it is worth untangling: is it them you want, or their approval? Do excellent work for its own sake, find mentors beyond one person, and keep the relationship strictly professional. Everything in the section on a married coworker applies here too, and their say over your career makes a confession riskier still. If you would still like it said, an IF keeps it out of your working relationship: it stays sealed while either of you is marked as in a relationship.
If your boss is the one flirting — messaging late, suggesting drinks for two — you do not have to respond, whatever you feel. Their power over your work makes any pressure their responsibility, not yours. If the attention is unwanted, note what happened and when, and talk to HR or a union representative.
Someone who reports to you
If you have feelings for someone you manage, hold every line at work. Never flirt, hint or confess: they would have to weigh their job against their answer, and nobody should be handed that choice. An IF asks nothing of them while either of you is in a relationship, but be honest about the power gap. If you are single and the timing lines up while you still manage them, you can let it lapse rather than reveal it, because a reveal from their manager would hand them that same choice. If the feeling ever colours a decision about their work, step back from that decision.
When the feeling will not fade
For most people, a work crush softens with time, a full life and a little distance. If yours does not — if you plan your day around seeing them, reread their messages or struggle to concentrate — it may have tipped into something heavier. That is not a character flaw, and you do not have to manage it alone: talk to someone.
And if you would rather move on, that is valid 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.
Where IF fits
A work crush is hard partly because there is nowhere to put the feeling. You carry it through every meeting, every coffee run and every Friday drink, and the person it is about sits a few desks away. IF gives it somewhere to go. It is a dating app for everyone, single or in a relationship, built on 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. While either of you is marked as in a relationship, no chat can open, so nothing on IF can ever become a secret between you. But you can still say what you feel.
Openly confessing to a colleague would be irresponsible, a gamble with two careers. If you are comfortable with it, an IF is the responsible version of the same courage: a private, sealed message of up to 250 characters that reveals only once you are both single. If you are single, it stays sealed while they are marked as in a relationship. If they become single while you are still single, you get 24 hours to reveal it, or you can let it lapse and stay hidden for good if the timing at work is still wrong. If you reveal it, they choose whether to accept, and accepting opens a chat with your IF as its first message. Being in a relationship yourself does not rule you out either: your IF reveals when you mark yourself single, as long as they are single too.
Mind the workplace side, though. If they are on IF, they will usually be told an IF is waiting — never who sent it or what it says — but in an office, people can guess from context. Use only personal details they chose to give you, never a work email address: an IF sent to the email of someone not on IF triggers one short invitation email, and a work inbox belongs to the company. One sent to a phone number or Instagram handle sends nothing, and simply waits in case they join. Withdrawing an unrevealed IF is a paid feature; membership has the details. And if it ever does open, a relationship with a colleague carries its own risks — your employer’s policy, a reporting line, a team that notices — so it is worth knowing the rules before that day comes. The choice is yours.
Your first IF is free, and how to send the perfect IF will help you find the words. Then it does the waiting: you say it once, mean every word and 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 wrong to have a crush on a married coworker?
No. A feeling is not a decision, and working closely with someone makes one more likely. What matters is what you do: keep it professional, avoid time alone that would read differently if their spouse saw it, and never let it become cheating or a lie. And if you would like them to know one day, an IF can hold it until you are both single.
How do I stop having feelings for a coworker who’s taken?
You rarely switch a feeling off, but you can stop feeding it. Cut the one-on-one time and late messages, mute them outside work and put your energy into friends and plans of your own. Saying it once in an IF can be what finally lets it rest. If it will not soften, talk to someone.
My coworker has a girlfriend but flirts with me. What should I do?
Keep your replies friendly and professional, and do not let it become anything you would need to hide. It may mean something or nothing, and their relationship is theirs to handle honestly. If you want them to know how you feel without bringing it into work, an IF waits, sealed, until you are both single. If the attention is unwanted or will not stop, talk to HR.
What if my coworker becomes single?
If you sent an IF while they were taken and you are still single, this is the moment it was waiting for, and it respects the room they need: once they mark themselves single, you get 24 hours to reveal it or let it lapse, and they choose, in their own time, whether to accept. If you did not, give it time. Someone fresh out of a relationship needs room, and a colleague needs to be able to say no without it following them into work. When the moment is right, treat it like asking out any colleague: once, lightly, outside work, and not while one of you manages the other. Our guide to dating a coworker covers how.
Can I get in trouble for having a crush on a coworker?
A feeling is not misconduct. What employers act on is behaviour: harassment, favouritism, or a relationship that breaks their policy, especially within a reporting line. Read your company’s policy, and keep your conduct as professional as your intentions.
