probably just used you or doesn't respect you anymore for being too easy. sorry thats how some guys are
I can't speak for what he's thinking, but I can say that he has some serious issues. <br />
He probably does care but his shame probably outweighs the care
Don't expect him to ever be any different
He must have regretted having sex with you. That's what happened to one of my girlfriends when she had sex her boyfriend became unresponsive after their first time.
he's just afraid he hurt you is all... he may be a bit concerned about it but it doesn't mean he cares for you personally
