My boyfriend and I broke up a few months ago and for the past month we've been having this thing. It's not a friends-with-benefits thing, it's just that we still treat each other like were together, and I honestly wish I could get back together with him. The one thing that holds me back is what he did to me that made me break up with him. At the time he had befriended this girl, which I felt was a threat to our relationship and she has a bad rep of getting around and playing with boys. We were going through a rut at the time with many problems and arguments and I told him it wasn't a good idea to be friends with her especially when I heard she had the intention of fooling around with him for no reason. He didn't believe me and in the end put her over me. Since then I've built up a wall and put my guard up. Since then, we have mended some of the issues within that problem, but sometimes we do rehash that awful memory as were fighting or having a dispute over something relationship related. Homecoming is coming up and I was forced to go with someone under certain circumstances. My guy, now, is asking this girl that he's starting to get interested in, or so I think he is and I'm scared. We still treat the kind of relationship we have as a girlfriend/boyfriend relationship, so it means a lot to me. He tell me he loves me and that she means nothing and that nothing will happen, but I can't believe that. Ever since our break up its been hard for me to trust him and I just can't do it. Am I just supposed to be okay with it and let him go with her? It makes me so upset, because I'm honestly just scared of a repeat of what happened and I really don't want that. Someone please help me to cope or find a solution to the problem. I really love him, and I WISH he could see how upset it makes me, but he really wants to go to homecoming which is understandable and I feel like I'm being selfish and unfair, considering the fact I'm going with someone as well.
