Well shoot. I don't how I missed that from Artista. I spent nearly all morning on that post, so I guess it passed each other somehow, IDK.
I may wrong, but I'm not sure confronting over the phone about the A right now will do one bit of good. That's why I pondered over what to say to her, b/c you don't need to show all your cards at the moment. This about her lack of respect, and she has gotten out of control. She is going to hammer you, trying to get you to crawl. She wants to wear you down.
Okay, just stay strong and don't give in, no matter what she threatens. Like you said, you can't identify with this level of sociopath.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
