This is why there are so many nasty guys out there ... because they get burnt by teenage girls and (unlike chicks) often guys who are hurt emotionally find it really difficult to ever move on. A number of my ex-boyfriend were like this. It makes me mad - we women expect decent guys, but equally we treat them like doggy poop.

Your friend needs to GROW UP and if she were my friend, I wouldn't be afraid to say so!
