Hi AKA Brian, welcome -- you've found a group that definitely understands that divorcing a person with a PD is challenging at best.
If you haven't seen it yet, check out the book
Splitting: Protecting yourself While Divorcing a Borderline or a Narcissist, by William A. ("Bill") Eddy, Esq. Many members have found it incredibly helpful, because when a pwBPD is involved, it won't be a "typical" divorce, and you need different tools and skills.
Where are you at in the divorce process? And do you share any kids with your spouse?
