My friend is going thru a divorce with a toxic ex. They were together 10 yrs, married 7 one 6 yr old boy. She had him taken out of the house in the middle of the night in front of the child alleging stalking. He won that case. He also won 50/50 custody. She is now on the parenting app the minute she feels she can accost him. One example is him getting the child a haircut w/o consulting with her first when he has been doing that right along. Another is he forgot to send a coat to school. The child worn a sweatshirt and no call from school. Lastly she reached out to his father to vent about the issue about the coat. His father has never been close to her and doesn’t really care for her. My friend tends to get reactive and respond to her to try to correct her behavior which will NEVER happen. I think she has Borderline PD but never dx but definitely narcissistic. What is the best way for him to respond on the parenting app and what responses will cause her to react. Everytime he farts she consults her lawyer. Also I know she is using the child as collateral and the child gets the impact when he returns home but nothing provable at this point. Any advise from anyone who has been thru this will be appreciated 😊
