If i was wrong or she was...?

This can't be a serious question. And if it is - leave her alone and stop harrassing her. She is entitled to talk to who she wants. She's made it clear she wants nothing more to do with you, and sadly you only have yourself to blame for that. You are a possessive, abusive bully and she is better off without you. Move on, but first get a handle on your temper and learn to control your behaviour before you enter another relationship.
