Your therapist is one of those idiots out there in the world who thinks that there is no reason for a child to cut off a parent. I really want to smack people like this because it makes me ashamed to have almost totally cut off my abusive, narcissistic mother.

In the end it doesn't matter what anyone else thinks. If he's crossed too many lines, then don't feel bad about not calling him. My mom's birthday is coming up soon, and I will call her to wish her a happy birthday, but no, I won't be seeing her and I won't be getting her a gift. Contact with her will likely dwindle even further in the near future.
