When One Partner Changes

The Hidden Pact That Can Make Growth Feel Like Betrayal

Roland Y. Kim, Ph.D.

About This Book

Personal growth is usually assumed to strengthen a relationship. Yet therapy, recovery, a new career, stronger boundaries, illness, loss, or a changing identity can destabilize a marriage that had quietly organized itself around complementary roles. Growth can feel less like improvement and more like betrayal of an agreement neither partner knew they had made.

What You’ll Explore

You’ll examine the hidden developmental pact, why complementarity can feel so good, how stability can conceal developmental debt, and what happens when one partner grows first. The book considers three broad futures of a developmental pact—restoration, dissolution, and transformation—and uses relational and historical examples to explore how partnership can reorganize.

Who This Book Is For

For anyone whose relationship has been unsettled by therapy, sobriety, recovery, career development, new boundaries, changing family roles, or psychological growth—and for readers who want to understand why one person’s development can threaten an otherwise stable couple.
