I am not sure how much he knows. When I was first diagnosed. I was obsessed with reading as much as I could about it so that I could understand myself. I bought books, read online, etc... I would ask him to read something, and he usually seemed uninterested, or would say that he was busy and would do it later.

I am not sure if he ever did. He has a problem when anyone asks him if he did or will do something. He has this great way of turning everyone else in his life into a nag.
