My understanding of passive-aggressive behavior has to do with a person’s inability to freely express anger as a child and learning how to express that anger in less direct ways that avoid confrontation but still make that anger felt. the origins of these feelings, which involve a parent who was full of control and/or rage and would overpower any display of anger on the child’s part with his own full force of anger. This made it unsafe for the child to express anger as a child. So now as an adult, he learns to go along but make his anger felt in indirect ways, including sarcasm, humor, irritability, and withdrawal. Now, in his adult relationship with a partner, with help can see how acting in the same way as he did growing up is causing conflict and unhappiness
