Negotiating collaboratively in your committed relationship is a new way to achieve individual and marital goals, to resolve differences equitably, to manage conflicts, to create and sustain a satisfying sex life, to figure out where you stand on fidelity, to think about having and caring for kids, and to have committed careers and a satisfying family life. Negotiating collaboratively supports you and your partner seeing yourselves simultaneously as individuals and as a couple—enhances the sense of “being in this together” while also having individual life plans. Negotiating collaboratively supports valuing each other as individuals before seeing each other as husband and wife, and allows modern couples to challenge old gender trappings that can undermine the achievement of balance in a committed relationship. Straightforward and accessible, offers couples a road map for how to negotiate collaboratively around the most essential aspects of a committed relationship—and, in doing so, create the equitable marriage they long for.
