Last term my boyfriend of 4 months broke up with me by text and then started being really unpleasant towards me. To be honest, I was more upset by his behaviour after we split up than by the actual fact that we'd split up. I won't go into all the details, but he thinks I am stupid for wanting to try and be friends. Two months after we split up, I got together with someone else. My new boyfriend is great, but I still feel very bruised by the last break-up. Apart from the fact that my new boyfriend is a normal, nice enough looking guy and my ex is absolutely stunning, the current boyfriend beats the ex hands down in every single way. He's nicer, more caring, more interesting, makes an effort to get on with my friends, wants to spend lots of time together, he's fun, we have a laugh together, he's better in bed... the list goes on.
Last night I went to a rowing ball and my ex was there but my current boyfriend couldn't go because he had another commitment. For most of the evening I had a good time with my friends, but I couldn't help but notice that my ex spent the whole night dancing with a mutual friend of ours and they looked very much like a couple. A lot of rumours go round about her and various guys, which I've always dismissed because she has a boyfriend of more than two years and I just always assumed she wouldn't cheat on him and that the people talking about her were just jealous and small-minded. But last night it looked like she really would cheat on her boyfriend, and this, combined with a few other niggling thoughts about his friendship with her and his history with certain other people, made me wonder whether he cheated on me either with her or with someone else, and whether everyone knows and thinks I'm an idiot. At the end of the night I went up to him and said hello, and he was fairly rude to me, although I'm not sure whether he meant to be, but that was upsetting too, although I think I managed not to show it.
I have no real way of finding out the truth, because if I thought he might have cheated on me with someone else, she's the only person I'd really feel comfortable asking. But for obvious reasons, I can't talk to her about it. Especially since she'd be really hurt and offended if it's not true. So I guess I can't do anything. But I feel really bad (and disloyal to my current boyfriend) for getting so upset about something which should be very firmly in the past. After the ball I went to my boyfriend's house and stayed over, and I felt like a horrible person being there with him but being upset about my ex. He knew what I was upset about because I told him, and I hate telling him I'm upset about my ex because I know how it makes him feel, but I feel worse not telling him what's on my mind. But selfish for telling him because although it makes me feel a bit better, it hurts him.
I hope this makes sense! Anyway, I was wondering what your thoughts are. I feel like my bad experiences with my ex (which I can't get away from because I can't get away from him) are threatening to spoil my current relationship. I feel I could achieve some sort of closure and be happier with my current boyfriend if my ex would just talk to be and be friendly, but he doesn't seem able or willing to do that.
What would you do in my situation?
Thanks
