Do you think this is appropriate therapy for anger with this issue?

My mom has borderline personality and is trying to learn to express her emotions in constructive, healthy ways. At no point should your husband be made to feel like a bad person because he's angry. One of the biggest problems among people with bpd is a feeling of worthlessness and him felling guilty every time he feels anger can only make his disease worse. And yes it is a disease. No different than if he was diabetic and no doctor would tell a diabetic their disease isn't severe. You should definatly look into finding a different therapist and may even want to consider a psychiatrist because the are real medical doctors. I hope this helps you and your husband.
