Just wanted to add some (((hugs))) - I can't imagine how tough it must be for you.
My only thought would be that maybe he needs reassurance to get him through this really difficult time of huge changes, and that maybe what you should do for the time being is go with the flow? You need a break and he needs a break, and maybe the best thing is to let him sleep with you if he needs to, at least while you both catch up on some sleep, and then tackle the issues arising from that at some point in the future when you are stronger and he is feeling more secure.
Hope you have some good friends and family to help you through this.
