How do I get him off my mind?

So here’s the short version of my story. I was seeing this guy for 3 months and he broke things off with no warning, so it seems. November is when we started to hag out more often, I really started to like this guy, and he was completely not my type. Anyways, come December we were texting everyday, hanging out all the time, and thats when I really started falling for him. New Years he broke up with me because he got scared, he had just gotten out a serious relationship. A couple days later, we kissed and made up. I found out he cheated on me in late Jan, early Feb, I found the underwear myself. Yet, I still gave him another chance, thinking, hey maybe he’ll change. So everything was okay after that, infact, we were better than ever. Then comes the end of Feb, he tells me ‘I think I’m losing interest.’ After being crushed on 2 seperate occasions, I freaked out, went to his place, and grabbed everything of mine. That was a month ago, yet we have talked ever since, we kinda turned into ‘friends with benefits’ although, it wasnt that for me, and sometimes he tells me its also not for him. He then told me he loved me, then the next day tells me he hopes he didnt lead me on. I got angry and told him I didnt want to talk to him again. Why do i still have hope in this guy, even though he treated me like a piece of ****? I still want to be with him and its killing me that he wont make contact, but i feel like i cant contact him, because then ill seem like i lost. if this makes sense to anyone..how do i deal with this? what do i do to get him off my mind??
