I see some pretty sound advice here. I'm really just trying to keep from getting my neck broke by this maniac, not trying to be some dang hero. I'll have a talk with her and either go somewhere else or stop seeing her whatsoever. She is going to have to do something though. We are simply just friends, I assure everyone. Thanks again everyone.

1...stalking her/you
2...she is telling him.
