Couple × Couple Developmental Interaction Library

This library examines what happens when two intimate partners bring different developmental organizations into the same relationship. A pairing is more than two individual stages: attachment needs, defenses, boundaries, power, care, autonomy, conflict, and repair interact to create a distinctive dyadic system.

How to use the library: completed pairings open into detailed matrices. Case Examples show how a pairing can unfold dynamically. Unfinished combinations are marked Coming Soon. Direction can also matter when the partners occupy different functional or protective positions within the dyad.
