Jealousy is a universal emotion—just like love or fear. It often arises when we fear that someone might come between us and the person we love. And when jealousy takes the reins, it can make us unhappy, push us to say or do things we regret, and even destroy relationships. Leahy normalizes this universal experience, validates the emotion, and describes its evolutionary adaptiveness. Jealousy is related to “parental investment” and the protection of our interests in passing on our genes. It relates to our natural tendency to protect our interests regarding family, friends, and colleagues. We feel jealousy because we care deeply about someone. Drawing on the tried-and-true principles of cognitive-behavioral therapy, the author offers practical steps for overcoming jealousy. He teaches the reader how to distance themselves from jealous thoughts and break free from unwanted behaviors. Particularly important is his guidance on how we can free ourselves from the shame caused by our experiences with jealousy. Being honest with ourselves is an important first step in taking responsibility for our behavior. Leahy’s book is aimed not only at those who suffer from feelings of jealousy but also at those who, unfortunately, are on the receiving end of it.
