Therapy today. Therapist suggested that "be the best you you can be, and put all your energy into your daughter" which pretty much everyone here is advocating is great advice and the best path forward. She was very much NOT in favor of the DB "tactics" saying they weren't exactly positive behavior.
It's two weeks until our next meeting. Hopefully little enough will happen in the next two weeks that I can actually spend less than 40 of the 45 minutes flapping my gums.
