After 21 years of marriage, Paula says she's thinking about divorcing her husband, Jeremy, because, in her words, he's "clueless, absent, and non-verbal." But Jeremy says the real problem is Paula. He says not only is Paula controlling, but she's a grudge-holder, too, and won't move on from a mistake he made almost 10 years ago. Find out the mistake Jeremy made, and Dr. Phil gets to the bottom of why Paula is so controlling. Plus, Dr. Phil and Robin share the secret to their 45-year marriage.
