I know it's hard to see it, but if he hurt you, you have to forget about him. Try making new friends, you may even meet a new partner. Understand that you are a good person who does not deserve to be treated so poorly. You are better than him. Do not let the part of you that wants to get back together with him take over you. Block him on facebook, and block his number. Erase him from your life, and let it be a lesson that some guys are nice, but some are cruel and never let yourself be with another guy like him again.
