She wants to file not you. Cooperating is different than being proactive. Let her file, the L send docs, you participate as needed and required. But don't go full out stuff to push it along before required.
I see detaching differently. It should be easier since she's so erratic right now. If she was of sound and sane mind then it would be more difficult as she would still look like your wife. This person isn't so detaching should be easier.
If you say nothing or just validate (but not agree) you aren't a doormat. You participating and getting into these non-winnable back and forth bickering makes you a doormat. Controlling yourself and what you participate in shows you having self control and self respect.
