Idoubt it, don't blame yourself. From what I remember of your first post, this guy didn't treat you well, and you deserve better. This relationship has probably taken its toll on your self-esteem, and it's causing you to think less clearly about him.
Going out with friends will help, working out, getting outside and enjoying the weather if it's nice, staying active and busy. I've also found that writing it all down in a notebook helps, once I get the thoughts out of my mind and down on paper, they tend to stay there.
Some people even read empowering relationship books. One of my girlfriends swears by "He's Just Not that Into You".
Feel free to stay on LoveForum and rant if you need to.
