Had sex with this guy haven't heard from him?

I have a crush on this super hott guy.. which he knows I like him, since its so obvious lol.. Well he told me he has a gf.. and I see em once in a while but I don't think he's interested in me. One night we were hanging out with a few friends and drinking, and he tried to have sex with me but I rejected him. Well after that saw him a few times and all until my cousin lied to his friend and told him I had went back with my Ex.. (since I didn't want him to think I was sprung on him) lol so when he found out I went back with my ex he finally wanted to see me again.. ( he had been kinda avoiding me) so after that we ended up having sex since we were both drunk at a kickback that my friend threw.. I haven't heard from him since then.. what's going on with this guy??!!.. I'm going to see him again eventually.. He's also told me Im attractive and compliments me if I'm wearing something nice. and checks me out when he sees me.
