Well, when thinking about breaking up, never take the other party into consideration. Obviously she will have to rent smaller, worse location etc etc. That's just life. She will figure it out.

2 things you need to think about:

1. If you're honest with yourself, do you want to break up or do you want to give it one more shot? Based on that question, you know what to do.

2. if it's the latter, think about what can possibly fix your feelings: did you fall out of love because of the cheating thing, or because you... just fell out of love as that can happen? Find the source of the issue, so you can work on it.

PS: honestly, I haven't been cheated on, so maybe I'm out of line here, but being bitter after 4 years, when she "only" kissed a guy and she confessed out of her own volition, that seems a bit extreme to me. Again, I can be wrong here and maybe cheating is cheating, no matter the 'gravity', but try to find inner peace with it, because how you are living emotionally right now, that's just not healthy.

Although your feelings are obviously valid, it's never a good idea to force your partner to cut someone out (unless it's about super bad issues, which this isn't).

Yes, he has tried, and probably will try. On the other hand, he has respected the boundary for many months too, because he probably figured out, your gf will not give in. It's not clear in your story why you got angry though. He's been respectful and he drove her home after a night out, without anything having happened other than some normal talks... Don't be the jealous gf.

In any case, trust your partner rather than distrusting the guy. I think your partner is more than fair to agree with only seeing him on family matters. Be grateful you have such a partner!

Conclusion: shake these feelings as you've reached another healthy agreement (first the boundaries, now the limited contact). If you say 1 more thing about it now, it seems like you're the toxic, jealous gf... Be mature, get past it.

You're asking for a character analysis on a guy we don't know. Impossible question to answer.

The closest I can tell you is this: I've seen good, honest guys do stupid stuff they probably regretted afterwards whenever the "environment" was badly encouraging them. In my case: put 20 soccer guys into a dressing room and once those kinds of talks start flowing with some beers, some things shouldn't be shared (just shown, or thrown in a whatsapp group chat).

So yes, it is possible he will share it to brag or have his "moment de gloire", even though that could be out of character.

It's also possible he's a decent guy who will lock this in his phone until he's bored of it and deletes it some months later.

You never know.

You will never know truly. People can act weird when their buttons are pushed.

If he's not your partner who you truly trust (and even then...), best to ask him to delete it.
