My boyfriend and I have been seeing each other since November of last year. I knew he just stopped hooking up with his ex, but I just broke up with my boyfriend too, so what was the harm. We started hitting it off, but about a month and a half later I found out he made out with his ex. I took him back since we weren’t technically dating. He never really did anything else sketchy since we’ve been together except trying to talk to her a couple times. BUT in May he broke up with me and went straight back to his ex, but he got back with me shortly after and blocked her. After that situation, he saw her twice, once during graduation and this one time at church. I saw him just staring at her for such a long time. It hurt, but he just said he was seeing if it was really her. I never really was worried about it until now. I currently live with him, he says he wants a future with me, and he is absolutely sweet to me all the time, but I just have this pitiful doom that it’s not going to work out and he’s gonna get back with her again. I cry and have panic attacks when her name gets brought up, and I don’t know if I can stay with these trust issues and insecurity. Is this a rebound? Is there a way to help my insecurities? Or should I just leave?
