my story... opinions needed?

[Mimi]

I was with a guy for 3 years, he was studying in my country, then he left to his, we decided to get married in a year. So basically that year was long distance relationship with few visits. Just a few weeks before having to come and propose and a month before marriage. We had an argument. Later on he called me, told me i'm immature, said a lot of nasty things about me and my family (though they took him like his own son and his family never even took their time to know me or my family), he said i ruined his life, when i told him he is important to me and i want to solve things out. He said we would talk in two weeks and left to his friend in other country, didn't hear from him in a month, he was ignoring me, wasting money, getting drunk with girls. Basically found out through his friend that he told everyone we are done, wrote on his fb that is looking for another girl, just before he left and talked a lot of s**** to mutual friends. He never talked to me again, he was always rude and disrespectfull whenever i contacted him and once i asked if he has a girl he called me a stalker, just lately after four months he wrote me he is happy and in a relationship. I actually have a feeling he was with this girl before we broke up. His family hates me for no reason (well the reason is different religions) and i believe this girl is their idea. How come after all this time, i'm still hurt meanwhile he is happy? How come i'm dreaming about him every night and whatever i do i cant get over all this? When i heard about the girl i wrote him a simple message that with his behaviour he made sure to erase all the years we had. But why I heart? He treated me bad and now he is happy and i'm miserable? I still love him, i wish everything was different, but what he did showed me he didn't care, he even sid that i loved him more and i wouldn't be a girl he would kneel to and so on... I feel really bad and depressed still after almost half a year
