Chassidic Jews create separate developmental lines for males and females beginning at three years of age. Since early marriages are encouraged and there is minimal contact between the sexes prior to marriage, problems inevitably arise in relationships. This article discusses both newlywed and long-term married Lubavitch Chassidim in couples treatment with secular analysts, parameters necessary for successful treatment, and countertransferences that arise. It is part of an ongoing series of publications based on the authors' decade-long psychoanalytic work with this population.
