Dear BB:
Without making any arrangement to see her, let her know that her behavior, and be specific about the nature of her behavior (outlined here, in your original post), has been making you miserable and you don’t want to be exposed to any more of it. Then let her talk. If she doesn’t talk: if she ignores what you just told her, or blames you in any way for feeling what you do and for sharing it with her, do not make any arrangements to see her.
Once you share with her what I am suggesting that you do, it is her job to consider a change in the specific behavior and tell you that she intends to do so. If she doesn’t express something promising to that effect, let her go, is my advice.
