Verbal abuse usually happens in private. It leaves invisible scars. There are no bruises, broken bones or black eyes. Often there are no outside witnesses, which makes it easy to deny. Generally in a verbally abusive relationship, the abuser denies the abuse.
Verbal abuse is a crazymaking means of dominance and control.
Although some verbally abusive people never physically abuse, physical abuse is always preceded by verbal abuse. I do not appreciate your insulting me and laughing about it. I am really tired of this. Then, repeat the question until you get a straight answer. I will get back to you later when we have calmed down.
