I'm going through a break up right now, and it's not made any easier by the fact that my friend is acting out on her crush on my ex. Today marks 2 weeks him and I have split, and she's been awol. We haven't spoken, and it's been confirmed by a few friends that she's now hanging out with him constantly. I feel betrayed, and hurt. Is there anyone out there who's dealt with this, and has advice on moving past?
