love and advice

Erin
First, I'm 15 and got with my boyfriend when I was 13. During that time he cheated and lied and we went through a few breakups. I recently found out that he had lied to me about being on drugs and being with girls. Today, I broke things off for good. He usually tries to save us, but didn't this time so now i know it's for good. He always has a group of girls that he runs to once we breakup. I gave him the world and tried to make him a better person but it was never enough. I obviously love him. Losing the attachment is hard because we don't talk now and it just hurts. Should've mentioned this earlier but we were also broken up this past summer but talked the whole time so it wasn't so bad. I just don't know how to deal with missing talking to him and seeing him with girls at school. He told me this time he would change but I didn't want to wait around to get my heart broken again. Advice on getting over him after 2 1/2 years?
