Mark...I can understand your wanting respect. I would like the same thing in my sitch.
Given the point you're at, and the fact that you dont care about the money, I'd say just sign it and be done.
However...this could be a good time to set a boundary with regards to her disrespect for you. I'm not good at doing that...but others here are so amybe they will chime in and help you set one that will hold.
