Advice on getting over bf hooking up with a girl during break up?
So me and my boyfriend broke up in December and got back together about 3 weeks later. During that time he had sex with another girl. I found out about this about 2 weeks ago by reading through his old Snapchat messages between him and this girl. I saw her nudes and everything they were saying to each other. Now I am trying to move on from it because we were broken up and he really wants to continue to grow with me. He says he regrets it and did it because he was confused during the break up. We're still young, 21 and 23, so he felt that maybe there was something that he was missing out on which is why he did it (that's what he said). He said he regretted it after and he realized he couldn't replace me, and there was nothing or nobody that made him feel the way he feels for me. I really just want to move on from the situation, but I can't help but feel bothered about the situation. Does anybody have any advice on how to move on from this situation and stop thinking about it so much??
