I'm sorry *** happened again from your brother. He sounds like a disturbed person who has no sane judgment and has very low morality. Yes he is an addict, but that is no excuse for anything and family or not, he sounds really toxic and abusive.
You know what I would do? Send those pictures and his letter back to him with a clear note asking him to never contact you again, and nothing more, nothing angry or frustrated, just that. Might also help you keep your resolve later vs not responding or not doing anything and getting tempted to reconnect when you are feeling lonely again.
That file Dee linked is really good, do check it out!
