Help me, I'm confused! Does he like me?

Okay, so there's a guy that I like. I've only known him for about a month now, but we've hung out a couple of times. When I'm with him, the conversation flows really easily and he's funny. Nothing feels forced or awkward. It's really very refreshing to be able to talk and joke with him and I really enjoy spending time with him. The first night we hung out we may have gotten drunk and had sex....and we've slept together one other time since then. But, when we hang out now it doesn't seem like he just wants a booty call, it seems like he genuinely wants to spend time with me and have fun.

He's super bad at messaging, though. Like he'll go days without replying, so I'm afraid to message him...I don't want to be annoying. Sometimes I feel like he's not interested in me, like one time when we were hanging out he randomly started talking about how he would make a bad boyfriend...even though I had, at no point, said anything about dating him. He's got me feeling a bit crazy, if I'm going to be honest. I feel like he's "too cool" for me. We grew up in very different cliques. He was the "popular" boy in highschool while I've always been the black sheep.

I'm just super confused. I think he's sending me mixed signals...or maybe I'm just not reading him right (lord knows I'm oblivious when it comes to dudes). I want him to like me. I even want to relationship with him (which is a big deal because I make it a point not to date anymore...guys are assholes). I don't know what to do.

Plus. I'm not bored of him yet....this is legitimately the longest I've ever gone liking someone without getting bored of them! Help me!
