For me, I had to continually remind myself that my BPD ex was sick and even the thought of contacting me brought her a ton of disordered thinking.
Think of it this way. Let's say you're allergic to cats. But every time you go to see your ex, everything is covered in cat hair. You know you're going to sneeze, to cough, to have allergic reactions. It's horrible. But you have to go there to get your kids...and the kids will also be covered in cat hair since your ex is literally the "crazy cat lady".
That's sort of how it is for BPDs. They realize deep down that they did you wrong, it brings them lots of anxiety, so they do things trying to control the situation.
Your ex is very sick. Have compassion for her and help her whenever you can. That changes the dynamics entirely. I'm not saying to go out of your way for her like when you were married...I'm just talking in passing when you're in front of her for kid handoffs or whatever.
