Hi
Gatvol,
Welcome to our online family.

I'm really sorry that are you going through this. It sounds like it's been a long road for you. You're definitely not alone in what you're feeling. Many here are fed up with the drama and struggle with their emotions towards their pwBPD.
Are you able to have a glimpse of your dad as a person with value and ignore the behavior, yet still maintain healthy boundaries? What might that look like in any interactions you may have with him?
