Hi Inertcheese998,
Nice name

Abuse toward my son was the final straw that got me to leave, too. The verbal abuse was insane.
It sounds like you were able to get primary custody and she has limited visitation? What's the schedule like?
People with BPD tend to struggle with boundaries, especially when dysregulated, which isn't surprising with a fresh divorce on deck. I'm guessing you don't read or respond to the emails at 2am... .
How is she able to shut off your power?
What are the main ways she is costing you attorney fees? I had a high-conflict ex (who happened to be a former trial lawyer), and he keep me in court for 4 years. I did learn a few things to curb the legal abuse, although it took a whole lot of effort to shut it down completely.
Does your son have a counselor? I wish I did family counseling with my son, although I'm a bit surprised that this isn't suggested by therapists. It certainly doesn't seem to be typical.
For me, it did get better, thanks to what I learned here from friends and other people who walked alongside me while I figured a few things out.
Glad you found the site.
