DnJ is absolutely correct...if he returns home, treat him as you would a roommate. The roommate takes care of himself/herself in all aspects of life. You only speak to him when necessary and if he speaks to you. reply in a calm voice and do not go to great lengths in discussions. Keep them short and to the point.
About the storage locker, you have advised him of where his stuff is and what he needs to do. It is not on you now to play mother and/or wife to him...he fired you in the wife department. Be sure to send your email about the storage facility and his response to your lawyer. No more emails and/or responses back to him except to say, you may address your concerns with my lawyer. You don't want to give him any more ammunition against you using the written word.
Take a huge breath and hold your head up high. Do not let him see that he is getting to you. I don't know how they do it, but they can sense our fear and will use it against us. Don't let him see you sweat.
Keep the focus on you and your children.
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.
