Tread, sorry things have gotten so rough for you. I do recommend you take the photos down. It'll be good for you.
I'm not sure telling S13 about the A is for the best. I can see telling other adults who may be affected by the sitch, but telling S13 almost seems like you want him to know how horrible his mother is. I understand that feeling, but in spite of everything, she is still his mother.
