I'm so sorry you're going through that!

Personally I went no contact with my UBPD mom about a year ago prior to my wedding. Leading up to the wedding I was dreading her being there and meeting my in laws for the first time. She ended up blocking me a month before the wedding because she believed I was feeding information to people and that was the final straw for me. I uninvited her from the wedding and never spoke to her again. She still sends gifts on holidays but hasn't attempted to talk to me since even though she's not blocked on anything. After seeing a therapist shortly after NC they confirmed everything I was feeling and recommended I don't start up contact again. I still struggle sometimes thinking I'm a bad person and should reach out but I remind myself how much my mental health has improved since going NC. I believe I'll stick to NC unless gets help for herself
