How can I get a guy to see me a certain way? (GUYS!!)?

My ex and I had a really bad break up, he went through my phone and found me texting some stupid perv at school, and we broke up. We didn't speak for months, but recently became friends. We're becoming really close, and he told me I'm one of his best friends. He always makes fun of me (in a joking way though) and is constantly grabbing me and pushing me around. We were drunk and hooked up, and ever since then, he's been coming close to me and kissing me, but in a joking way. He obviously wants to hook up with me, but I want another chance to go out with him. He knows I like him and I care about him, how can I make him see me as more than a friend, but not JUST a hook up? He acts like he likes me and wants me, but then he REALLY liked another girl, but she just got a boyfriend. How can I get him to like me like that? Thanks!!
