Hi Blue Jay,
I'd liek to welcome you to bpdfamily. I'm sorry to hear that, being in court with a pwBPD is incredibly difficult, the system is built so that it's you vs someone else, it creates conflict and it's more difficult when someone has a high conflict personality, not to mention that it's unwarranted attention.
What are his boundaries when it comes to money? Is he getting fleeced in court or is he giving into her demands?
