Dr. Sue Johnson opens by applying attachment theory — originally developed to understand parent-child bonding — to adult romantic relationships, arguing that couples' emotional bonding and conflict patterns follow predictable attachment dynamics.

Why this attachment framework matters for understanding couple dynamics:

• Attachment theory provides a well-researched psychological framework for understanding how humans form and maintain close emotional bonds, originally studied primarily in parent-child contexts
• Johnson's application of this framework specifically to adult romantic relationships, developed through her Emotionally Focused Therapy approach, provides a research-grounded lens for understanding couple conflict and connection patterns
• This opening establishes the book's core theoretical foundation, distinguishing it from more purely behavioral or communication-technique-focused relationship guidance

This opening establishes the book's foundational attachment theory framework, providing research-grounded structure for its subsequent guidance on understanding and improving couple emotional bonding.
