Whit~ I'd be hurt. flat out, that's what I'd be it sounds like she wants to please both you and her bf and her bf...is moving up the chain so to speak. Especially if you have the feeling that she wasn't even going to tell you that she wasn't going to come. I'm sorry that she's being like this it's tough when you have a good friend that sort of "loses interest"....
