Your H is not going to admit or want to discuss ore even acknowledge to himself the good that was in your marriage because it invalidates what he is doing now. WAS's need to live in and remind themselves of the negativity (real or perceived) of the marriage so that they can justify their actions of walking out.
I'd take some focus off of him and re-energize yourself. Move forward on some things that you want for you. You don't need to be stuck in limboland and moving forward doesn't necessarily mean you are completely giving up on the marriage - it just means you refuse to stay stranded in the hell you are currently living in.
