The Wednesday Group by Sylvia True

Five women find themselves joining a therapy group because their husbands are sex addicts. There's Gail, a judge, whose husband is tempted by his female students, and Hannah, whose young daughter, Alicia, is acting out because of the uneasiness of her parents' marriage. Rounding out the group are Flavia, whose husband has been arrested for groping someone on the subway, and Bridget and Lizzy, who both are struggling with anger and frustration towards their husbands and worry if the men are being honest. With therapist Kathryn to guide the weekly meetings, the women slowly confide in each other about their lives and emotions and find themselves forming a bond.  A good read-alike for The School of Essential Ingredients and The Friday Night Knitting Club.
