Sadly, I think your son needs a new group of friends. This girl that he used to date? Trouble, in my opinion. That's the only thing I can come up with in response to your statement about how he was 'being nice to the other girl so he could get laid."
That's really crappy of his ex to do to him. I would be careful how much time I spent with these friends if I were him - yeah, that's one rumour that he can dispell easily, but what happens if a bigger rumour is made, and he can't fix it easily? He's better off without Miss Drama. Candi, who liked some of her teen years, and is suddenly glad she's only ever dated two guys.
