I had that happen once. My ex-best friend. Long story short, she flipped her s**t and accused me of acting like this girl who totally made her suicidal. She's just an insecure b**** ( I dot NOT mean this in an offensive way. This is just how she acts to people) and she is a total drama addict.

I had been really close to her, and she saw me at a store, I know she did, but instead of saying hi, she just left and ignored me.

Then, of course, when we started to drift apart, she would start asking my best friend to go do things with her (because I had been friends with both of them) and they would exclude me.

So, this is the advice I offer, in the nicest terms possible: F*** her. I apologize for the brash language, but seriously, if she's going to act like that, she is NOT worth your time anyways. I learned this recently and I am just now working on weeding out those from my life who are nothing but negative energy.

Yes, she might have been busy, but... You never know. Just cut your losses, is what I would do.

However, I do apologize that this happened to you. D: It is a pretty bad feeling.. D:
