Passive-aggressive behavior is the expression of negative or hostile feelings in an indirect manner. In its extreme it is a form of emotional abuse. Many narcissists use this type of behavior as their primary communication tool because they are deeply insecure, angry, and terrified of direct conflict. Dealing with passive-aggressive people is crazy-making. No one’s needs are adequately being met and because communication is covert, you often can’t put your finger on why it makes you feel so frustrated and upset.
