Contemptuous behavior (e.g., eye-rolling, sarcasm, and name-calling) in your marriage is the highest indicator that you are headed for divorce, according to Dr. John Gottman, founder of The Gottman Institute.
Dr. Gottman has conducted 40 years of research relating to the dynamics in spousal relationships, and is well-known for his “Four Horsemen of the Apocalypse” theory—that if you or your spouse react to conflict with criticism, defensiveness, contempt, and/or stonewalling, divorce is likely in your future.
