Work it out Girl.
I spent two years trying to figure out wth was going on with my business partner. I kept coming to NPD websites when I searched the specifics of how I felt, what she did and how to deal with it.
I spent a good year trying to convince the people around me that she was a nightmare. But I couldn't get away.
Finally, in one week, three people told me, "You I would follow anywhere. But that Bitch has to go." Literally the same thing. I was just about to sign another partnership agreement with her.
It snowballed from there and today I'm free of her and the abuse I endured, happy to look the other way and not focus on her at all anymore because now that I'm doing that, amazing things are happening.
Hugs to you.
