Thanks again all, I did speak with a couple of lawyers last year. Neither of them were familiar with personality disorders. It was frustrating because one of them... had a blog with a couple mentions of high conflict personalities but when I talked to her, she was oblivious to NPD or BPD.
I had a two year divorce and was in and out of family court for another six years. Court studiously ignored the obvious mental health issues. As did CPS, police, children's hospital, etc. They all danced around the core issue and looked at only their slice of responsibility. The unstated expectation was that it would eventually fix itself.
Even my lawyer, as practical and experienced as he was, ignored my concerns that that I was dealing with a Personality Disordered ex-spouse. Yes, he did call her batsh-t crazy, but like most everyone else in the system PDs were never voiced.
The only exception was our last magistrate. Fortunately she was no-nonsense and didn't put up with my ex's antics. Unfortunately, we had her only at the end of my eight years in and out of family court. While she did lambast my ex for disparaging me in my son's presence, did grant most of the solutions I sought in my petition and even said my ex needed counseling, she stopped short of ordering counseling.
There was a lesson there.
Family court does not try to fix the adult litigants. It deals with them - mostly - as they are. We would do well to follow that pattern. Its court orders are what we would otherwise call Boundaries.
If we do head down the path of divorce, I am still hanging onto some hope that we could work through some mediation.
Fortunately most of your issues are financial except for the long term guardianship of your needs but grown son. There are calculations for alimony but beware of agreeing to open ended orders. They tend to continue for longer than appropriate. In decades past long marriages could end up with permanent alimony, not so much today. (One member long ago said his former state may still be an exception.)
The point is that today spousal support during a divorce or alimony afterward is seen more as interim support while the financially disadvantaged ex
transitions to life after marriage.
Be aware that laws in the USA changed a few years ago. The income earner now pays support and the income taxes, not the recipient who earns less and may be in a lower tax bracket. The government wants its cut.
In my own divorce my ex easily agreed to a financial split since she was possessively focused on the custody and parenting issues. But she balked on the parenting. There was a chasm between our perceptions so the mediator agreed that mediation had failed. I learned a lesson then...
It's okay if mediation fails. That is better than agreeing to lousy terms. In our cases mediation often does fail and the litigants simply return to court and report mediation failed. The good thing for you is that court has calculations to handle the financial issues. However, be careful not to let the court walk all over you when trying to find a quick fix.
