My ex was physically abused by his stepdad. When his grandparents got custody, she took him for three sessions. The first session he saw his grandmother go in afterwards and talk alone with him. He refused to talk to the therapist after that. He told the therapist that he wouldn’t talk to someone who talked about him behind his back. So he was silent for the rest of that session. Grandma took him back and then silence the next session. Then grandma never sought therapy again.
