Perhaps you should check out SuperDuperWonderBoy's post at the bottom of the page. He is saying goodby to R because his WW is only doing the bare minimum and, after two years of her just not doing enough, he has realized that this is not the way he wants to live the rest of his life.
When you're starving, ribs showing and unable to move, you need to be fed carefully to recover. You need steady food, nutrition, rest, exercise, and encouragement, step-by-step, to recover. You need to be carefully nurtured and watched, if your partner wants you to recover.
If all you get for nourishment is an occasional feast, then a carrot, then gruel for days on end, you will not only NOT get better, you will get worse and possibly die from a perforation of your digestive system. To reach health, you cannot be treated hap-hazardly, with little care of attention.
Your marriage is that starving person. If your spouse isn't doing enough to help it to heal, then he's doing it damage. And doing you damage.
