I have been struggling to get over a short relationship that ended about a year ago, although we were in quite regular contact (via messages) for a few months after that, and getting back together was mooted. Contact ceased completely this May.
At first I thought he was great and that it was going to turn into something long-term, but increasingly he started to be demanding, manipulative, insulting, argumentative, unreliable, unwilling to do things together and he even physically assaulted me on one occasion (I wasn't hurt).
In the end I gave up trying to make things work because it seemed barely a day would go by without him taking offence at something innocuous (one example - I bought him a birthday present as a surprise, instead of checking with him what he wanted) or doing something weird.
I haven't had a successful relationship for well over a decade and I find this very difficult and painful at times as it's something I want very much.
The other day I bumped into him and it turns out he's now in a new relationship and "very happy". I just don't understand how he can have morphed into a loving, reliable partner who is meeting his girlfriend's family (I never met any of his friends or family). Meanwhile I am of course still single.
I feel tormented. Why could he not treat me in this way? Why can't I find a partner? I really don't want to continue living my life like this. It seems so unfair that he is happy and I am utterly miserable.
I know this sounds dramatic and probably as if I'm about 15 (reversing those digits would be more accurate), but I just seen to keep repeating a cycle of relationships that last more than two or three months. I feel ashamed of that and very, very unhappy.
I have had therapy and it doesn't seem to have changed anything. Just keep going feels like running a marathon. I don't know what to do.
