You miss the old him and he is not that person anymore. I have to keep telling myself that as well. It is so hard to see them change into something you don't like anymore.
As far as the moving, I say do what feels best for you. If you just need to move and not tell him til afterwards then do that. Sometimes you just need a break to save your own sanity. I'm sorry this is so hard for you right now.
I agree though, just when you think you are doing so well, something else comes up. We are in for a long haul so it won't go away for quite a while. When it gets this tough, take it one thing at a time and remove the bigger picture from your head.
Try to do something nice for yourself today. Sending positive vibes your way Aa.
