My boyfriend had opened up to me about why he doesn't speak to his mom. Her face is cut out of all the pictures he has and the one where she was holding him in the hospital when he was born was, he burnt her face out of it. She had started sexually assaulting him when he was 12 and going through puberty and telling him this was sex ed and she was just teaching him about his body and the female body. And she was doing that by doing sexual stuff with him and having him do sexual stuff with her. He didn't find out it was wrong until he started going to public school in High school and he tried to commit suicide over it. I've been trying to be very supportive of him because it took him such a long time to tell me. He sees a therapist online because of Covid. Well my Instagram is set to private so it alerts me every time someone requests to follow me. His mom requested to follow me. I was wondering if I should tell him or would that be too triggering and I should just block her and not say anything. I'm trying really hard not to trigger him and I want to know if telling him may do that?
