You can't control what he does, says or thinks. You can only control you and how you react to his behavior. Whether you tell him where you are going or not...well, there is no way to predict how he will react. Hence, I think you are over analyzing and focusing on the what if's. By doing so, are you walking on eggshells? If so, you need to step over those broken eggshells and reclaim YOU.
He's going to do whatever he needs to do to make himself feel better. Right now, you've been fired as his wife and friend. Treat him as you would a roommate, i.e., be polite, talk just a wee bit and go on about your business. If he wants to know something, he will ask you.
Keep the focus on you. Keep the focus on today and allow tomorrow to reveal itself when it is ready.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
