Well, in my opinion, based on what you have said, I think you have tried, anyway. She sounds toxic to me.

Is there anyway you can not go to the same places she does? I guess you want to go to the baseball games, etc., though.

If this matter gets more troublesome, then you might want to talk to a therapist about her. I know one time a woman called me and said all kinds of abusive things (even threatened my husband), and my therapist said if she called again to just hang up on her! I didn't expect that. We even got the call feature that let us know who is calling after that. Thankfully, she didn't call again. I guess I didn't act scared and give her what she wanted or something. Whatever.....
