PLZ ANSWER i'm going crazy this guy was so obvious but now hes not and im really confused i cant stop thinking?

It sounds like he may have lost interest, and just wants to be friends OR he just wanted to "get some"? sorry, this sounds mean, and I'm not intending it to sound mean. But that's just how some guys are =/, ya know? I say to go for another guy, and forget the ones who mess with girls like that.
