They live with me full time so when she starts on a texting spree they just ignore her. Then she will call and they will be very short with her because they are annoyed. Then I get text messages that they are being mean. Yes you read that correctly. She says they are mean to her like she is a teenage girl.
I, totally believe you I have 2 step daughters that live with their dad full time and have an uBPDmom. The immaturity and drama are real

If they know it's going to provoke an emotion they will wait until they are at the T with mum. Obviously when the ex is there she has to be on her best behavior so they drop hard topics there and then leave.
What is really good here is that you are clearly trusted by your kids and that you have them in Therapy. That will help them with coping tools, a neutral party to listen, and someone who can help them negotiate their mother. It sounds like they are also able to identify some of the things that trigger their mother.
Do you see your kids creating boundaries in terms of their mom? That could be helpful. My significant other's (SO's) younger daughter is low contact with her mom, she has phone/text contact because she needs that distance from her mom. She will occasionally see her mom for lunch or coffee but always in a public place (so like your wife at the therapist she is on her best behavior).
Then it's all my fault because everything in her life is my fault even though she left us and had a secret lover. Which is weird because my T told me "just because she had a secret lover doesn't mean she wanted the marriage to end". That one left me scratching my head.
I can actually understand this. People with BPD run completely on emotions... .emotions of the moment. Each person seems to have their own brand of BPD (combination of symptoms/behaviors), some cheat and others like my SO's undiagnosed BPD ex-wife (uBPDxw) have problems/self sooth with money, for others it's drugs and alcohol. So her secret lover makes her feel good in the moment but she still wants to be wife and mother. My SO's ex felt good spending the family's rent/grocery money on things... .it made her feel good but she still wanted the rent paid for and the groceries bought. No thought at all about consequences... .that would be logical... .there is no logical only emotional.
Have you done much reading on BPD? That was the first thing I did when I discovered it... .went straight to the library. It was really helpful to get a basic understanding of BPD.
