I am not trying to be harsh- but whether or not you believe in divorce, you can't make someone stay in a marriage that doesn't want to be there. You gave it an honest go, you did your best, and that is nothing to be ashamed of. But if he's not in the same frame of mind as you, the sooner you accept that things are changing (and take the best steps necessary to protect yourself and transition into a new life), the quicker you will recover and move on to a better, more authentic life. It may not seem like that right now with so many unknowns, but you can and will get there.
