I have a problem that I am looking for advice with. About 2 months ago I broke up with a guy I had been dating for 3 years. A ferw weeks after that I began dating another guy and we are still dating happily. The problem is that I can't seem to get my ex out of my head. Normally I'd disregard what I'm thinking but when I think about it it makes me sad and makes me wonder whether I am with the wrong person. When I am with my current boyfriend I am so happy and I love being with him and spending time with him but when we are apart all I can think about is whether I made the wrong decision in breaking up with my ex. I'm not sure what to do. Should I just keep moving on and eventually I'll get over my ex, or do my thoughts about my ex mean nothing? Or should I try again with my ex? I dont know what to do and its really bothering me. I'm completely lost...
