Talking About Your Ex in a New Relationship
Entry No. 185 ·

By The IF Team
In a new relationship, share enough about your exes that your partner understands you, and not so much that your ex moves in with you. The broad shape is usually enough: how long it lasted, roughly why it ended, and what you took from it. Mention anything that affects your partner now, such as an ex in your friendship group or one you still speak to. Leave out comparisons, intimate details and a running commentary. Bring it up gradually as things get more serious, in a calm moment rather than a heated one, and when they talk about their past, listen with curiosity rather than cross-examination.
If you have been dreading the moment the past comes up, that is natural. It can feel as if you are being asked to defend a previous version of yourself. But talking about where you have been, with care, is one of the ways two people become close. In diary studies of everyday conversations, the psychologist Jean-Philippe Laurenceau and colleagues found that sharing feelings built intimacy more than sharing facts, especially when the listener responded with understanding. The point of talking about your past is not the facts. It is being known.
It is also worth saying plainly that feelings about an ex do not always tidy themselves away on schedule, even when you are happy with someone new. That is human, and it is part of why IF exists. IF is a place to be truthful about a feeling — yours, about anyone, whether you are single or taken — so that something that started off-screen, in your actual life, can be named today and acted on only when the moment is right.
Why the past comes up at all
Your history explains a lot about you: why you hate surprise parties, why you text back quickly, why a certain tone of voice makes you tense. Without some of the story, your partner is left guessing at the reasons for things. Talking about it also avoids nasty surprises. Finding out from a friend that your partner was engaged, or that their ex lives two streets away, stings far more than hearing it from them.
What to share
- The outline. How many serious relationships, roughly how long, and roughly how they ended.
- What you learned. “I realised I need someone who talks things through” tells them something useful about you and nothing unkind about anyone else.
- Anything that touches your life now. An ex in your circle of friends, one you still message, shared belongings or a lease you are untangling.
- Anything that shapes how you react. If a past relationship left you wary about something, saying so helps them understand you rather than misread you.
- The big facts, eventually. A previous engagement, a long relationship that ended recently, a breakup that still hurts. These are hard to hide and harder to discover.
What to keep to yourself
- Comparisons, in either direction. “You’re so much better than my ex” is meant kindly and still invites a contest nobody wants.
- Intimate details. Your partner does not need a highlights reel, and your ex deserves some privacy too.
- Their secrets. Details your ex told you in confidence are not yours to share.
- Endless venting. Some processing is natural; making your new partner the audience for every old grievance is not fair on them.
There is a difference between private and secret. Choosing not to share every detail of your past is private, and healthy. Actively hiding something your partner would reasonably want to know is secret, and secrets have a cost: in a large set of studies at Columbia, the researcher Michael Slepian found that the burden of a secret comes less from hiding it than from how often your mind keeps returning to it. If there is something from your past that you keep thinking about, that is often a sign it wants saying.
When to bring it up
On a first date, keep the past light: a sentence, not a saga. Deep conversations about exes early on can make a date feel like therapy and leave both of you wondering whether the other is really over anyone. Over the first months, as you get closer, the fuller picture tends to come out naturally, often prompted by a question or a memory. Before things become properly serious, it is fair for each of you to know the main outlines.
If you are asked something directly, answer honestly, even if briefly. “It’s still a bit raw, can I tell you properly another time?” is an honest answer too. Choose calm moments for the bigger conversations, not the middle of an argument, and never as a weapon.
How it can sound
You do not need a speech. A few examples of the tone that works:
- “I was with someone for about three years at uni. We grew up in different directions, and it ended pretty kindly. I learned a lot about saying what I need.”
- “My last relationship ended badly, and I’m still a bit guarded sometimes. If I go quiet, that’s usually why. It’s not about you.”
- “I should mention that my ex is part of the friend group you’ll meet on Saturday. We’re on good terms, and I wanted you to hear it from me first.”
When they talk about theirs
Listening well is half of this. Ask questions that help you understand them, not ones that turn their past into evidence. “What did you learn from that?” is generous; “Were they better looking than me?” is not. Try not to keep notes for later, and resist the urge to measure yourself against someone you have never met. Their past relationships are part of how they became the person you like.
If something they share leaves you with a flicker of insecurity, that is normal, and it is worth saying gently rather than stewing on it: “I know it’s silly, but hearing about them made me a bit wobbly.” Most partners respond warmly to honesty like that. If you are about to meet the friends who knew them with their ex, meeting your partner’s friends has a little advice on handling the moment when the ex’s name comes up.
The harder cases
If you were cheated on in the past, you may find yourself wanting to explain why you need reassurance in certain situations; dating after being cheated on looks at how to rebuild trust without making a new partner pay for an old one’s choices. If an ex is still very much part of your life, as a friend or a constant presence in your group, be open about it early, and agree together what feels comfortable.
And if, despite loving your new partner, you still think about an ex more than you expected, you are far from alone. Still having feelings for your ex in a new relationship is a common, human situation, and it is worth understanding before you decide what, if anything, to do.
Where IF fits: a past that is not quite finished
Some feelings for an ex fade the moment you meet someone new. Others linger quietly: the one that ended because of timing, the one who moved away, the one you never fully said goodbye to. None of that makes you disloyal. Memories and feelings betray nobody; cheating and lying do.
If one of those feelings needs somewhere to go, IF offers an honest one. You can write it once, as a sealed message of up to 250 characters, and send it to them as an IF. There is nothing wrong with sending one to an ex, unless they have asked you never to get in touch or you are both keeping to no contact. Just do not treat it as a second go at a no: it tells them what you feel, and what they do about it is up to them. While either of you is in a relationship, no conversation can begin on IF, so it is not a line back into the past; it is a feeling put on record and left to wait. If your ex already uses IF, they may be told an IF is waiting, without being told who sent it or what it says, and it opens only on the day neither of you is with anyone else. For the bigger question of whether to rekindle anything, reconnecting with the one that got away is the place to start.
Whether you mention it to your new partner is entirely up to you. Sending an IF is your own private business: you are not obliged to tell your partner, or anyone else, and keeping it to yourself is not doing anything wrong. Some people like to be open about an ex, and that is a fine choice too. If you do send an IF, the first is free.
Questions people ask
When should you tell a new partner about your past relationships?
Little and lightly at first, more as you get closer. A sentence on an early date is plenty. Within the first few months, as the relationship becomes serious, it is fair for both of you to know the main outlines, and anything that affects your present should come up sooner.
Do you have to tell a new partner everything about your past?
No. You are entitled to privacy about details, and some things are not only yours to share. What a partner reasonably needs is the shape of your past and anything that touches their life now. Keeping some things private is healthy; hiding things that matter is where trust starts to wear.
Is it bad if a new partner talks about their ex a lot?
Not necessarily. Someone who has recently come out of a long relationship may mention it often simply because it filled so much of their life. If it is constant, or full of anger or longing, it is worth a gentle conversation about whether they have had the space to move on.
How do you stop comparing a new partner to an ex?
Notice the comparison, and then ask what it is really about: often it is a fear of repeating a hurt. Spend your attention on who your partner actually is rather than who they are not. Over time, new shared memories crowd out old ones, and the comparisons fade.
Share the shape of your past, listen to theirs and keep the present at the centre. And if a feeling from before is still unfinished, an IF can hold it honestly, sealed, until its time comes.
