It's a relief for Alice to admit she is addicted to alcohol. She's been hiding it too long. Her husband is warm and understanding, arranging for her to check into a treatment facility. It's after Alice starts being sober, that’s when her husband starts showing signs of being unhappy. Michael shows how much in love he is, how attentive, how accepting. Sure, she hid a lot of her drinking, but the drinking she couldn't hide, the episode with the eggs, the scene in Mexico, the night she locks herself out of the house, which would be unacceptable to many spouses.
Alice checks herself into a treatment facility, where she begins learning to live with the disease. She makes close friendships with other recovering alcoholics. On visiting day, when a fairly fearsome-looking fellow patient offers to play with their daughter, she reassures her husband: "He's not a child molester. He's an armed robber." Back home, Alice attends a lot of AA meetings, and confides in friends she meets there. Michael is not sure he likes this so much. They have fights, mostly because Michael still has the habit of handling everything, settling problems with the children, making decisions.
