I feel the exact same as the three of you - today is one of those days I am hating my H and what he is putting us through with his crazy MLC and trying to figure out how this happened. There was not much wrong with our marriage before all this crap started - it was good. Maybe not great but not much to complain about.
Still, I also know I made vows before God and I intend to keep them and will NOT lift a finger to undo them myself. For whatever reason God has allowed this in my life I have to trust that He has great plans for my future, whatever that may be.
I also have days where I feel great, confident, etc. but then there are the bad days. And today is one of those.
