Is he using me?

So there’s this guy I really like. Neither of us are a fan of hookups but we talked about being friends w benefits. He hung out and just talked for like 4 hours. Then I sucked his dick and then we were kinda having sex but we stopped in the middle and he was just like “idk man” etc.

does this mean he doesn’t like me? Or is he just not into it because we both don’t usually like hookups? Does he want more, should I leave him alone??

So in my head!!
