I’m reposting this in hopes of it getting a little bit more traction. So my ex and I had been together since we were 14, were happy throughout high school together, went to colleges 3 hours apart and made the long distance work until this past weekend. We had been having some issues but managed to work through them and had a great weekend together two weekends ago, but then this happened. She slept with a guy she knew but wasn’t necessarily friends with. Keep in mind, we had only had sex with each other and have practically grown up together and she completely crushed me by doing this. I broke up with her right when she told me because I have respect for myself but it’s been a really tough week. She feels awful for doing it and wishes she could “take it all back”, it’s just unfathomable that she threw away our LTR for a one night stand. It wasn’t a guy she was consistently seeing, apparently it was just a “spur of the moment” thing, but I’m not even sure if there’s any truth to that. We haven’t spoken in two days and I’m continuing the no contact but it’s been really hard so far. Anybody out there been in a situation like this? The hardest part for me is that we had only ever been with each other and she showed horrific judgement and got intimate with a guy behind my back. Any advice on moving on? Should I even entertain that this was a one time thing and try to save the relationship?
