What's a wife to do he's driving me crazy .?

Has he always been like this? If not try to find the root of his anger and talk about it with him. Is he over stressed? Are you over stressed? Autistic children have more needs, and if your over stressed or he's is over stressed weather it be time or money it can cause anyone to become snappy and moody. Try planning a date night and talking to him alone about his anger. Maybe he doesn't realize he is being so over baring.
