Hi and welcome puzzlebug.
I'm sorry for your situation.
I think it's reasonable to lay down ground rules for your household - respectful dialogue - no raised vouces, no stealing, in by a certain time or a phone call to explain why not.
If he doesn't like it he can move out.
I know that may not be the kind of solution you want but it doesn't sound like him living with you and giving you nothing but grief is doing much for the family dynamic either?
