About the Book

Relationship Wealth: The Essential Needs That Predict Relationship Success — and How to Satisfy Them is a practical, research-driven guide by licensed psychologist J. Larry Caldwell to building a strong, fulfilling partnership that stands the test of time.

Based on an original study comparing couples who flourished with couples in distressed relationships, this book introduces the Relationship Needs Matrix — revealing the essential needs that quietly determine whether a relationship deepens or begins to break down. When these needs are understood and consistently met, connection grows stronger, trust becomes more secure, and love becomes more sustainable.

Inside you’ll learn how to deepen intimacy, communicate with clarity, and navigate challenges in ways that strengthen — rather than strain — your relationship. With practical strategies and real-world insight, Relationship Wealth offers a clear roadmap for creating a partnership that not only endures but truly flourishes.

Whether you’re looking to strengthen an already good relationship, repair what feels strained, or begin a new relationship with a solid foundation — this book provides the tools to help you build lasting connection and meaning.
