what should I do?

okay well there’s thing guy that I used to date and it seemed like he really liked me. he didn’t rush me into anything and me and him would talkin every single day for hours. but then after a while he started pressuring into doing things with him and then finally when I went pretty far with him sexually he just stop talking to me. after a while a couple of his friends said that he was just using me. well anyways it took me some time but I got over him. later after about a year I contacted him just to say hi as friends. but he took it a step further. he came and visited me and we slept together. he told me he was going to call me but he never did. a week later he was goin out of the country for a year to so I got so mad that he never called. anyways I’m just having so much trouble gettin over him again. I miss him so much. no matter how many guys I’ve been with I want him and only him. I don’t know what to do and if I should just let go or wait till he comes back and contact him again. I think he just used me again too but he’s just so special it’s his personalitly im in love with and I haven’t met anyone like him. I know I could get better looking guys and that’s why im suprised he doesn’t want me when I gave him my all.
