Dom, Fran's husband is an active alcoholic. The normal rules of relating don't apply. For an active alcoholic, the MOST important thing in his/her life is alcohol. It's important for Fran's husband to keep things in their life the same so he can go on drinking. If she changes things, he will have to make changes, too. By being "nice" to Fran, he is trying to keep her from making changes that might bring him face to face with his drinking. For her to appreciate what he is doing does not have the same meaning as it would if a normal husband in a normal marriage were doing something nice. Fran's H isn't doing it out of love; he's doing it out of terror that she will leave him, and he won't have a safe place to drink anymore.
That doesn't mean he doesn't love her. I'm sure he does. But he is not capable of showing it in a consistent, genuine way as long as he is not in some kind of recovery program.
