I'm sorry you and your husband are at different points on this. To me, waiting for a "good" day to leave is like waiting for a "good" day to quit smoking. There is always something on the horizon that makes it hard. If you wait a few days for the psychiatric appointment, you might then need to wait a few days for the referral, or waiting for a medical evaluation, or something else, and on and on it goes. Plus I think you lose all credibility if you don't follow through. What happens when you give him a new date? He will have no reason to think you mean it. I would have a different answer if you hadn't given him a month's notice.
