Book excerpt: A full one-fifth of the United States has engaged in consensual non-monogamy (CNM) at some point in their lives, and 29 percent of adults under thirty today consider open relationships to be morally acceptable—yet there are few resources to turn to when it comes to navigating this more non-traditional and explorative territory. Picking up where CNM self-help books like Polysecure, The Ethical Slut, and More Than Two leave off, Open Deeply tackles the most difficult challenges posed by CNM. Therapist Kate Loree—who has practiced non-monogamy since 2003, and who specializes in treating clients who also practice non-monogamy—pulls no punches as she uses vignettes based on her own life, as well as her clients’ experiences, to illustrate the highs, lows, and in-betweens of life as a consensual non-monogamist. Interwoven with these stories are thorough explanations of how attachment theory impacts non-monogamy, how blending cutting-edge, neurobiology-informed grounding skills with effective communication skills will make even the most challenging conversations regarding non-monogamy manageable, and more. The result is a compassionate, attachment-focused template for non-monogamy that will allow readers to avoid pitfalls and find adventure while concurrently building healthy relationships. Non-monogamy is a wild and woolly ride—and Open Deeply is here to help make it a great one.
