Why can't I move on?

You can’t move on yet because the breakup’s story hasn’t settled, even if your days have. Time helps, but research suggests that making sense of what happened is what really loosens an ex’s hold, and that’s something you can work on directly.

Why are they still in my head when my life is good?

Meet Ines, 33. She ended a three-year relationship more than a year ago. Since then she’s switched teams at work, taken up climbing, gone on a solo trip to Lisbon and built a Thursday dinner habit with two friends. She likes her life. And still, on a quiet Sunday, a photo of a lake they visited can knock the air out of her for an afternoon. She doesn’t want him back. She just doesn’t understand why he’s still here.

Part of the answer is that bonds to people we were close to fade slowly. In a 2025 study from the University of Illinois, adults whose relationships of more than two years had ended, on average in their early thirties, kept an attachment to their ex that faded gradually; it took a little over four years on average for that bond to fade halfway.1 So a lingering ex, a year or two out, is common. It doesn’t mean your life isn’t full. It means the relationship mattered.

What’s a fact, and what’s the story?

When an ex keeps showing up, it helps to split what you know from what you’re telling yourself:

• What happened: it ended, on a date you can name, for reasons you can partly list.
• The story: “I’ll never feel like that again.” “If I’d been different, it would have worked.”
• The fear: that you missed something about yourself, or that it will happen the same way next time.
• The next step: something you can do this week that’s about you, not them.

The facts are mostly settled. The story and the fear are where the energy goes.

Does checking on them keep it going?

Often, yes. The same Illinois study found that how long the bond lasted depended partly on continued contact with the ex.1 For a lot of people single in their 30s, contact isn’t dramatic. It’s still following each other, a mutual friend’s group chat, the occasional “happy birthday.” None of that is wrong, but each one is a small refill for a bond that’s trying to fade.

You don’t have to cut everything at once. Pick the thread that pulls hardest, the one you check late at night, and loosen that one first.

Why does understanding the breakup matter so much?

Because a loss without an explanation keeps asking to be explained. In a study that followed 160 young people from 20 to 25, those who had a clearer understanding of why their breakup happened had fewer internalizing symptoms later (the inward kind, like anxiety and low mood), and their later relationships went better too.2

That doesn’t mean finding one tidy reason, or deciding whose fault it was. It means being able to tell the story in a way that makes sense to you, including the parts that were nobody’s fault.

Why do I only remember the end?

Endings are loud. The last six months, the last fight and the last text tend to crowd out the earlier years. How you hold your own past seems to matter here. In a survey of 1,404 students after recent breakups, people with a warmer view of their past, what researchers call a past-positive time orientation, reported less breakup distress, as did those with secure bonds to their parents growing up.3

You can’t rewrite how it ended. But you can let the good parts back into the story without it meaning you want them back. “We had two really good years, and then it stopped working” is often truer than either “it was all a mistake” or “it was perfect.”

Does writing about it actually help?

There’s evidence it can. In a 2002 experiment, psychologists Lepore and Greenberg had 145 students who had been through a breakup either write about it expressively or write about neutral topics.4 The neutral writers showed short-term increases in tension, fatigue and cold-like symptoms, and the expressive writers didn’t.4 It’s one study with students, but writing is cheap, private and something you can start tonight.

What can you do tonight, and this week?

• Tonight: write for 15 minutes about the relationship, start to finish, including the good parts. No one reads it.
• This week: finish the sentence “It ended because…” three different ways, then notice which one feels truest.
• This week: pick one memory you’ve been avoiding because it was happy, and let yourself have it.
• Ongoing: when the ex shows up on a quiet Sunday, name it (“that’s the old bond, fading”) instead of treating it as a sign.

When is it more than a breakup?

If the sadness isn’t easing, or it’s disrupting your sleep, your work or your ability to get through the day, please talk to a licensed mental-health professional. And if you’re feeling hopeless or having thoughts of harming yourself, reach out to a crisis line now (one is linked on this page).

What doesn’t the research show?

• The four-year figure is an average from one study, not a timeline you need to meet.1
• The understanding, time-perspective and writing studies used young adults and students, so they suggest what may help rather than prove it for you.234
• None of this means you need to be fully over someone to have a good, full life now. Both can be true at once.
