I really empathize with you. I had someone a lot like that for a couple of years at work. She was in a senior position so no one could get her out. We called her the Alabama Tick since she was dug in so deep. To get anything done in her area, you had to bend the knee and kiss the ring. If not, she would get offended and make it impossible to get anything done.

Best wishes and blessings to you in this. I hope it works out.
