"She came in our room a little bit later crying wondering why I was ignoring her and why I hate her so much. I told her she was the one who didn't want me around her, or talking to her, and I didn't understand why when I respected her wish she was mad about that too."
This works. You ignore her and live your life happily the way you want to.
The fact that she wanted to give you soul custody of the kids shows that she's got some major issues. So start doing things with the kids on your own. Just yourself. Show her your self-sufficiency.
