Daphne de Marneffe, PhD, is a psychologist and the author of "Maternal Desire: On Children, Love, and the Inner Life." In her clinical practice, she offers psychotherapy to couples and individuals. She teaches and lectures widely on marriage, couple therapy, adult development, and parenthood.
In her new book, "The Rough Patch: Marriage and the Art of Living Together," she explores the pushes and pulls of midlife marriage, where an individual's need to develop can crash headlong into the demands of a relationship.
