In a perfect world, we'd all live happily ever after. But with more than half of all marriages breaking up, it's as though an unseen force drives husbands and wives apart. To find out what that "force" is-and how it can be stopped-Dr. John Gottman, a psychologist at the University of Washington, studied more than 2,000 married couples over two decades. What he discovered about how wives and husbands relate to one another is so remarkably revealing that he can predict-with 94 percent accuracy-which marriages will succeed and which will fail. Now, with this book, Dr. Gottman gives you a set of highly effective tools that will help make your marriage last as you more fully understand how it works.
