So me (18f) and my boyfriend (18m) are very young, I know that. Mistakes are bound to happen this young. Every time in any of my past relationships that I’ve been cheated on my family has told me that they’re young, I should give them the benefit of the doubt, etc. now my family thinks I’m wrong for giving my boyfriend the benefit of the doubt for being young. My boyfriend and I have not been dating that long but about five days ago, I got a message from a girl with about the same name as me (just spelled A bit different) and she told me and sent me screenshots of my boyfriend trying to get back together with her when they never dated in the first place they just hung out a few times. After a few days of not talking to him, I texted him asking him why he did it because I ended things with him at the time and I just had a lot of questions on why and when I broke up with him, I didn’t really give him the chance to say anything or explain himself at all I just told him we’re done and I blocked him and it was all out of anger because I didn’t try to talk to him or anything. But we started talking again to try and figure out if we can work our issues out and I do want to but I can’t stop thinking about the messages and the stuff he said to her and asking why and wondering why he did it and what I could’ve done different or what was going on in the relationship that he didn’t like and that’s why he did it, but his response keeps being I don’t know. he keeps swearing that he doesn’t know why he did it and he’s not gonna do it again. He realized how much it fucked us up and I do want to try to work things out with him, but at the same time with my family in my head saying that he’s just gonna keep doing it and he’s gonna do it again and all that I really don’t know how to feel because I keep just getting upset at him and yelling at him for not knowing why he did it because all I wanna know is why. please feel free to give advice, I really need it.
