Polysecure: Attachment, Trauma and Consensual Nonmonogamy

Jessica Fern adapts classical attachment theory to fit the specific dynamics of multiple romantic partnerships. She describes how traditional models prioritize monogamy as the only path to a secure base and introduces the concept of the nested model of attachment. This framework considers how individual trauma, cultural environments, and relationship structures intersect. Fern outlines a practical method for building internal and external safety called HEARTS, which focuses on behaviors like consistency, active engagement, and repairing trust after conflict within nonmonogamous networks.

Individuals navigating open relationships or polyamory read this to understand why multi-partner dynamics often trigger childhood abandonment fears. It serves those who find standard relationship guides exclusionary because they assume a two-person limit. Readers learn to identify their own attachment styles—anxious, avoidant, or secure—and gain specific techniques to manage jealousy and insecurity. The book provides a blueprint for maintaining emotional stability while managing the complexities of several simultaneous connections.
