How can i move on?!!

ok hi guys,

I have a it of a complicated relationship situation, please help me come clear with it.

I was seeing a guy for 7 yrs, now he is engaged to his cousin and due to get married soon.
the thing i don't understand i was furious when i found out, but i accepted it and tried to understand it.
I dont understand why, when i want to move on with my life he calls me names (Bt�H, w#ore, and all sort), always putting me down and compared me with his fiancee that she is better in everything than i'm, when i was here and was there through out everything, helping him from lil things to money, he never once helped me with my responsibility whenever i ask him for help he cant do it or never does help but i have to be there for him, like a wife or like his mother.

Now that he got a job and planning his wedding, i'm no good to him. and his fiancee is the perfect woman for him, ok i wont dispute that maybe she is. She is in different country, so it's more of distance relationship. I have read her txt sent to him , i swear she is playing him like a doll, i feel ike she has hidden agenda she says things which i wouldn't think of saying to him, how stupid is he to believe that she is innocent and all. he believes that she hasn't been out with any guy, how would she know some intimate things and the way she likes them done to her????:surprised

I was always there for him but never appreciated me never, he put me through a lot never once admitted or took responsibility of his actions towards me, he always jump to say " you're an adult you know what you're doing, i never promised you anything so why mad at me?" i dont want anything from him, but he wont leave me alone and move on. he isn't happy for me if anything good happen to me he'll criticize it and make bad comment. He is so envious but then he'll turn around and say all these sweet things to me. He confuses me, One minute im all he wants another i'm the worst woman he ever met, not to be trusted, or deserve worse in my life.

I'm furious inside i want to explode, i wish i could revenge back, the way he treated me. never appreciated me once.
How can i hurt him back the way he did?
How can I move on past this pain?
How can i forget him?
what should i do? it hurts to see him happy to hurt him and happy with his fiancee? It hurts so bad.

HELP please.

1. Why are you reading his text messages?
2. Why are you seeing him?
3. Why are you even talking to him?

From what you're saying, this guy is a screwed-up asshole. Why would you associate yourself with him?

1. I know i shouldn't have, it was out of rage and jealousy.
2. He comes back to me, as we were living together, he had spare key and i cant change my lock, i'll need to change the whole door. i cant afford it now.
3.i tried not to talk and advice him but as mentioned (2), its almost difficult.

I don't want to associate with him, all he does is bring me down and never want to see me happy or succeed in my life.
