I'm so sad for you, I wish I had comforting words. I just really feel it is time to let go and move on with your own life and give your H the time and space he needs/wants now. Staying is not going to be good for you and it is not going to fix him or change his mind. I know this is still very raw and emotional so I am not suggesting you make a plan right now but maybe over the next few days since he will be gone start thinking about what YOU want to do, where YOU want to live, what will make YOU happy. It's time to let go and live for yourself. I know that sounds awful but it is the only thing you can do now and it is ultimatly the thing that will save you.
I will keep you in my prayers tonight. I hope things look better in the morning.
