Really horrible break up, how do I get rid of him?

So last year in November 2011 we started dating, we were long distance but he broke up with me because he was still in love with his ex who he had dated for a year and a half, she was his first girlfriend ever,and he realized it wasn't fair to me. We became best friends after that and we talked every day, and he consulted me about everything, he said before me he had never actually talked about his emotions with anyone, not even her. He began seeing her for a little while, and she ended up not wanting him in December, which was the next time I would see him, after we hung out over Christmas break for two weeks he realized the feelings were still there, but we still remained best friends until March, which is when he asked me out. The day we started dating, his ex told him she still had feelings for him, he said he didnt like her like that, and that they should remain friends.So a week later she got a boyfriend.After five months he realized he couldn't do a long distance relationship and broke it off with me. A week later, his ex broke up with her boyfriend, so naturally he was into her again. After two months of not seeing each other, and only occasionally talking, I went with him for three days to cedar point with his family and some of our friends, I am very close with his family. He realized he liked me again and that he wanted to pick me over her, so I agreed to date him again. A week later he broke up with me because he couldn't do a long distance relationship, and then his ex came back again. Two weeks after that, now November 2012 he realized she was only playing with his emotions and he wanted a real relationship. He left her and I began talking to him again, and then he asked me out a week later, I saw him during thanksgiving break and we slept together. We were not going to make anything official until after Christmas break, when I would only live half an hour away from him and it would no longer be long distance. We were fine for a month, and he went to hang out with his ex and decided he had no interest in me and he liked her even though she was never physical with him and will not be till marriage,I was the first girl hed ever been physical with. later that day I found out she had a boyfriend. It is a week later and she is no longer in a relationship with her then boyfriend and they are all lovey dovey again.

Should I cut all contact with this guy?I feel like otherwise this will be a never ending cycle, especially since they will not be physical and he wants physicalness, so I feel as if he will come right back, especially living in the same town. What should I do?
