Well that sucks, sounds like you two were good friends for a while.
As I am not a woman I won't comment on the hows or whys of her acting this way, female relationships are a mystery to me. I never understand why you guys do what you do to each other sometimes.
I will say I hope she wakes up and realizes no guy is worth losing a good long friendship like that. I've only got one friend still around from 3rd grade, he's far away, but I still consider him a good friend even after 25 years, we've kept in contact and get together when we can. I hope you guys can patch it up
