How to get over a break up?

I've been talking to this guy since like May last year. We would talk evryday all day. Eventually I started liking him and he went and pulled this dick 移动 on me. As the retard I am, I took him back after he apologized and told me he liked me. After that, we had a "thing" for a while, went to the movies, all that stuff. Yesterday, he decided to end it and I'm really upset because now I dont think we'll ever speak again and to lose that friendship tears me up inside, we were so close and I still really like him even though everyone thniks the only reason he liked me was to do "stuff". Can anyone help 或者 give 建议 to get over him? I'm so upset :'(
