Do a quiet audit before you do anything public

Before you mute, leave, or type anything you will think about at 2 a.m., spend five minutes just looking at which chats actually involve your ex, which ones they are only loosely connected to, and which ones are genuinely yours. Not every group chat with a mutual friend in it is a landmine. Some of them, your college friends who happen to also like your ex, your book club that your ex attended once, are still fundamentally your spaces. Others, his college friends who tolerated you, the fantasy football league you joined to spend more time with him, were always more his than yours. Sorting them into those two categories, yours and borrowed, is the most useful thing you can do before any other decision. Write it down if that helps. A notes app list is not dramatic, it is information. What tends to trip people up here is the sentimental middle ground, the chat that feels shared because you built real friendships inside it. Those deserve more thought, and they get it in the next step. For now, just name what you are working with.

Mute or leave the ones that were never really yours

Research consistently shows that people who mute, unfollow, or limit contact with reminders of their ex do meaningfully better than people who keep the exposure going. This applies to group chats the same way it applies to Instagram. Every time his name pops up in a thread about weekend plans you are not part of anymore, you are not getting closure. You are hitting reset on the part of you that was finally, finally starting to calm down. The borrowed chats, the ones you sorted in the previous step, are the ones to leave or mute without ceremony. You do not owe anyone an explanation. A quiet exit from a group chat is one of the least dramatic things a person can do in the year of our lord whenever you are reading this. If leaving feels too visible because the app announces it, muting is a perfectly valid long-term option. You will stop being a participant in a space that was always more his than yours, and that is a boundary, not a statement. Nobody needs to know your reasoning. You barely need to announce it to yourself.

Have one honest, private conversation with the friends who matter

The mutual friends you actually want to keep deserve more than a quiet mute and a hope that they figure it out. Pick the one or two people in any given group who are genuinely yours, the ones who would call you first if something went wrong, and have a brief, honest conversation outside the group thread. You do not need to assign blame, deliver a verdict on your ex, or explain the entire relationship. What you do need to say is something close to: I am stepping back from the group chat for a while, and I wanted you to know directly so it does not feel weird. That is it. That conversation does two things. It protects the friendship from the passive awkwardness of just disappearing, and it gives you a real contact in that social circle who knows where you stand. What tends to go wrong here is people either saying too much, turning it into a deposition, or saying nothing and then feeling quietly hurt when the group moves on without them. A single, low-key text takes about four minutes and saves months of low-grade social anxiety.

Set a specific rule for yourself about checking their activity

If your ex is still in any of the chats you remain in, or if you find yourself opening old threads to see what was said after you left, pay attention to that impulse. Research on anxious attachment suggests that the urge to monitor an ex's activity is often older than the relationship itself. It is the same wiring that had you checking your phone constantly when you were together, waiting for a response, reading tone into a short reply. The group chat becomes just another feed to surveil, and every visit resets whatever quiet progress you had been making. A rule works better than willpower. Not a vague intention but an actual specific rule, something like: I do not open that thread after 8 p.m., or I wait 24 hours before reading any message that includes his name. The specificity is the point. Vague resolve dissolves. A concrete rule holds because you only have to make the decision once.

Create a small ritual around the ones you choose to leave

This one sounds stranger than it is, but stay with it. Research on grief and loss suggests that rituals reduce distress not because they are magical but because they give you back a feeling of control over something that happened to you. Leaving a group chat is a genuinely small thing. But it is also a real ending, and real endings sometimes want to be marked. When you finally exit the chat that held three years of inside jokes and shared plans and a version of your life you are no longer living, you are allowed to do something deliberate with that moment. Screenshot the last message you want to keep, then delete the thread. Make yourself a coffee before you do it. Send yourself a voice note afterward that just says: I did that. As we write in our piece on finding divorce support groups, the people who move forward most steadily are often the ones who take their own transitions seriously, even the quiet digital ones that nobody else sees. You do not need an audience for this. It is just for you.
