What do you do when your falling for a player? And I'm going to see him tonight please help?

So, about two weeks ago I met this totally cute guy at a club from a different school. We started talking almost immediately when we saw eachother and then I ended up sitting in his arms for the rest of the night, but we didn't kiss or anything. Then, the next Friday I went, and we just said hi to eachother, then in the middle of the dance floor he just sort of stared at me. And I stared back so we looked into each other's eyes. But then he was on like every girl at the club, I mean they might be just "friends" but still. Then one time he sat down on the sofa, and I went and sat by him and was like talking to him, but it seemed like he was ignoring me, or maybe I imagined it, so I scooted away. I don't know why, but the thing is I still like him and keep thinking about him, and I am going to see him tonight again at the club. So what should I do? And oh, by the way, we are in highschool.
