Ex boyfriend problems?

So me and my ex boyfriend went off and on for over 2 1/2 years [11/4/09-06-13-11] and now that i finally moved on i been thinking about him everyday and it seems like the more i think about him the more i want him back. Through out our relationship he cheated on me, abused me, was dating another girl for 7 months, lied, and disrespected me billions of times but i still stuck around until May 9th. May 9th i gave up on me and him i found somebody else, well actually they found me at my job. I started talking to this guy and my ex had found out about it so he went on and fought this guy because he was mad. After my new dude and my ex had fought i lost all contact with my ex. I changed my number and everything. As the month went by the girl he cheated on me with turned out to be his new girlfriend and they updated their Facebook status saying in a relationship with so and so then it said its complicated with so and so. Currently i looked and it doesnt say anything on his page idk about hers because i blocked her. I cant stand to see them two together but i feel if he cheated on me with her he needs to stay with her and leave me alone for good. His friend told me that he still is crazy about me but he doesn't like me. Thats fine but i really want to move on from him and erase him out my life forever. Its bad enough that i live right around the corner from him and i seen him today at the bus stop and i drove right past him. But i need HELP SOMEBODY GET ME OVER MY EX BOYFRIEND PLEASSSE SOMEONE I NEED IT NOW. Cus if i dont get help im going to keep bringing his name up and im going to want him again. I have a new dude i talk to the one he fought but i still think about my ex time to time. Can i get over him or am i going to be stuck on him for awhile?
