How do I deal with a situation in which my best friend starts dating the guy she knows I've liked for a long time?
She has been my closest girl friend for months, and has known for months that I like this guy. He is actually who I'd call my best friend. We're really close, and he knows me better than anyone.
About a month ago, I found out that she had been holding hands and kissed him, and then she revealed to him that I had feelings for him. When I confronted her, she promised me that they would just be friends because she didn't want to lose my friendship and she loved me so much and I was so important to her.
A couple nights ago, she told me that after we get back from spring break, they are going to start dating. She said she has developed feelings for him over the month or so since the initial incident, and he's asked her out numerous times and now she said yes.
They both knew about my feelings, and they know this hurts me. He told me he doesn't want to lose me, I'm his best friend, he loves me, all of that. I don't want to lose them, but I don't know if I should forgive them for this.
