Saturnpatrick, any update since May? You received lots of great advice at the time, so hopefully that's been helpful in moving forward and protecting yourself.
My story is a bit like yours. My WH's A 12 years ago, followed by what I now realize was false R. Second D-Day in December, and I filed for D. My divorce didn't include assault accusations, but WXH asked for $210k per year in spousal support for 10 years (!!!) even though similar to your WW, he has a graduate degree from a top school and more than ample ability to support himself. His narcissist tendencies, however, cause him to believe that the rules of life don't apply to him and that he's above having a job. 
The divorce process included lots of claims on his part, including his "not feeling safe" around me. And rewriting of history, including things that never happened. Plus numerous angry outbursts that even our mediator said were some of the more extreme he's seen in his career. I have to imagine that after thinking for so many years that XWH could manipulate me, play me, and control me, his angry outbursts came from realizing that none of his old tactics were still working.
My solution was to concede more than I could have in the divorce, in order to get it done fast. Some of the points mattered but ultimately weren't worth arguing over, so I decided my mental health and recovery was more important than winning every last battle. Of course, every situation is different, and there are plenty of smart reasons for a BS to fight hard in a D. So not sharing my experience as the solution that everyone should use - just offering one experience.
Hopefully your D is moving forward (or even has wrapped up) without more drama. Wishing you a great outcome.
