Original Poster, I noticed you said that your friend of 6 months was really nice to you, but then you say you think she stole him on purpose and pressured him into a relationship, which is not nice, so I'm confused. I pretty much agree with what everyone else is telling you. That he wasn't yours to begin with, you have a boyfriend already, and you knew him for 2 weeks. I am sorry you are hurting though. And I do think you have a right to feel your feelings about it. Feelings are feelings and we feel them regardless of logic. You asked how you can forget about her (my advice is to forget about him too). Make some new friends. Do some things you enjoy. Learn about the way life works (I don't mean this in a condescending way either. There are all things we need to work on and learn). I think someone here posted a link to moving on for you, which sounds helpful. I wish you the best.
