“That is why we think that self-justification is the prime suspect in the murder of a marriage. Each partner resolves the dissonance caused by conflicts and irritations by explaining the spouse’s behavior in a particular way. That explanation, in turn, sets them on a path down the pyramid. Those who travel the route of shame and blame will eventually begin rewriting the story of their marriage. As they do, they seek further evidence to justify their growing pessimistic or contemptuous views of each other. They shift from minimizing negative aspects of the marriage to overemphasizing them, seeking any bit of supporting evidence to fit their new story.”
