Book excerpt: After dealing with more than a thousand clients whose marriages have dissolved, Sexton knows all of the what-not-to-dos for couples who want to build-- and consistently work to preserve-- a lasting, fulfilling relationship. He dives straight into the most common marital problems, and shows how these usually derive from dishonest-- or nonexistent-- communication. Though he deals constantly with the heartbreak of others, he still believes in romance and the transformative power of love.
