One Night Stand or What?

So a few weeks ago I hooked up with this guy it started out as us just being cool friends and just having good convo then one night I got drunk and horny and we did it , after that it seems as though things have been different between us the texting and conversation as been different and I’m not sure if I did something wrong or if I’m not taking the hint I just need to leave him be....should I try and figure out what the deal is or just let it be whatever it is?
