Most often when a marriage is over, it's closing the door on an already empty room.
I think your room just became a little more empty LMN. You've tried and you've been patient, but you don't have to stay sick just because he is. It's okay to stay and it's okay to move on. And you don't have to do either today.
Take care of yourself and time and God will take care of the rest.
