Accidental romantic involvement with one of my best guy friends, I need a little advice?

Sweetie. Even the nicest of guys get horny. And yes,I think he was using you. You can live in denial if you want to. But I call it like I see it. He had NO problem letting you feel him up and vice-versa. However when talks of a real relationship start,he's not a bit interested. Girl....He's a player!
