Heres an update, turns out the guy did like her. Well, just like i told her, she might just be looking for a friend but its only natural for a guy whos single and hangs out with a hot girl would like her more than a friend.
She doesnt do anything with him anymore cuz shes angry at him, she thought she had made it clear she was in relationship and that he understood that.
Also to clear up the type of situation for you all a little, he didnt hit on her or try to make a move. He pretty much just told her that he liked her more than a friend or something like that.
And im not gonna go and beat the shit outta the guy or anything, i dont blame him, my gf is cute as hell.
I hadnt replied before because although all your comments are interesting it was getting farther and farther away from my situation.
