Does he like me or just want ?

Ok I know this sounds immature but I really like sum lad, were both 23 n know each other from the same pub. We have mutual friends n all came mine 4 a drink 1 night n we slept together. Since then we have ended up together a few times after drinkin, I know I shudnt sleep wiv him straight away but like him n just want 2 be near him. He comments occasionally on Facebook status' but nothin interesting, we occasionally exchange messages on fb but he never messages first, apart from sumtimes when hes been out at 3 in the mornin. How can I get him 2 see me as more than ??
