What do I do to fix my relationship?

I have been in a relationship with this guy for 7 years and we broke up in December and I am really hurt that he would lie behind my back and tell me things are ok in June when I moved out then 6 months later Find him Yahoo Personals. I am so confused I dont know what to do I was so angry with him today and I am still angry with him because a part of me wants to move on but a part of me wants to work things out with him but he wants to date other women. I have a good heart, very honest, caring, giving, not a taker, I do just about anything for this guy I am so confused on what to do. I still see him and go to his house but I really want him back but as of today I am not so sure anymore. He saids he is dating me too/wants to be friends but I dont want to be his friend anymore I want things the way they were before the break up. I want him back so much. I really love him so much but I am really hurt we got into a fight last night and I just dont know what to do anymore. Any suggestions?
