So there’s this guy I’ve been seeing. He says he wants to date but I know he just wants to hookup because of all the signs lead up to just a hookup. But anyways I told him that I’m starting to like him. We’ve had sex 3 times now. He knew my birthday was coming up the next day because he asked what I was doing. But then when that day came he never wished me a happy birthday. It kinda hurt that he didn’t text me or call me and he definitely knew. Should I be mad about that? Should I just move on and not care? Does that mean that he just doesn’t care anything about me and wants just a casual fuck?
