I broke up with this guy four or five months ago and still miss him despite the fact that he cheated around 11 times with various people. We were going out for a year and a half (18 months) and were really close friends before that. I was his first proper girlfriend and he was my first proper boyfriend, which I think adds to the heartache... The thing is, I feel guilty for dumping him because he was genuinely sorry and I know that, and also I know that he doesn't just go out with anyone, he really loved me. He has a new girlfriend now whom he seems happy with so I think I feel jealous, seeing as he told me before that it takes something reall special for him to have a girlfriend. the question basically is, should I still be missing him, feeling guilty, crying around four times a week over him, and wanting him back after four or five months?
