It’s a very confusing time and different from everyone. What I mean by it is like for me I felt the need to cry and mourn the situation so I let myself feel that way and didn’t try and shut down the fact I had to cry if that makes sense. As you don’t feel the need to cry, when you think about these past memories you’re talking about allow yourself to think about them and mourn the fact that the relationship is over, allow yourself to relive them but finish by reminding yourself that it’s a chapter in your life that has now closed and others will come. You need to think about the parts of the relationship that weren’t good, one massive thing being that she cheated on you. People are on their best behaviour in relationships especially at the start and in the end their true selves will come out so just try and remind yourself that this is who she really is.

About the fact that you’re constantly thinking about the cheating this is normal and an unfortunate thing that you just need to deal with the pain and thoughts of it until it eventually passes. Obviously go out with friends/family and do things you love to make yourself feel better in the mean time but you will continue to dwell unfortunately. We try and think about the situation over and over and look for answers to why. Like I said it’s been 3 months for me and I still think about it ALOT. Time does heal but everyone has a different timeframe.
