Verbal abuse defines people in some negative way, and it creates emotional pain and mental anguish when it occurs in a relationship. . . .
Any statement that tells you what, who, or how you are, or what you think, feel, or want, is defining you and is, therefore, abusive. Such statements suggest an invasion of your very being, as if to say, “I’ve looked within you and now I’ll tell you what you want, feel, etc.” Similarly, threats are verbally abusive because, like torture, they attempt to limit your freedom to choose and thus to define yourself. Of course, if you have defined yourself to someone, “I’m Suzy’s Mom,” and that person says, “That’s Suzy’s Mom,” they are affirming or validating what you have said. On the other hand, verbal abuse is a lie told to you or told to others about you. If you believe the lie, it would lead you to think that you are not who you are or that you are less than you are. . . .
Another common way the abuser defines his partner is by walking away when she is asking a question, or mentioning something, or even in the middle of a conversation. By withholding a response, he defines her as nonexistent. . . .
Defining statements are the opposite of affirmations, which are positive statements that confirm what we know and value about ourselves. For example, when a man says, “I hear you. I understand,” even if he does not agree with you, he validates or confirms what you have expressed to him. If, however, he says, “You’re too sensitive,” or “Where did you get a crazy idea like that,” he invalidates and defines you.
