don't talk to him, don't think about him, don't do anything that has a memory of him in it.. cut off all the ties that you and he had.. and realize that if he hurt you once.. he'll more than likely do it it again.. just have a small get away for a weekend and clear your mind and let everything out, either by writing or drawing or whatever helps you out.. and move on with your life and find a guy that won't hurt you.
