my ex friend was incredibly rude to me?

[Anj]

My ex best friend thinks she is too good to talk to me. When we were in college she was my best friend and we would do everything together. I moved to a new town after college and she went to graduate school where she made all these new friends. She told me "I don't need you. I have these other people who are my close friends now." I cried and I tried to rekindle the friendship but it was one sided. She posts stuff on facebook like "love my best friend. We talk everyday" about her new and some of her old friends. She just chose to dump me though and I am 100% sure I am the closest thing she ever had to a real friend. It drives me nuts though that she has all these new friends while n I have to struggle. Any advice?
