The other thing is when she manipulates other people to guilt you. "Why don't you talk to your mother. She's terribly lonely. You are a horrible son" can easily be answered with: "I set a clear boundary with her that I cut contact. She sends you to violate that boundary. This is precisely the reason I'm not talking to her".
Since normal people don't have BPD they will understand. That's how it was for me.
Remember one day she will be old and in a nursing home with not a single person visiting her.
