A very common aspect of psychological abuse and manipulation is for the abuser to claim that the victim is being abusive towards them. I’ve written about the abusers “victim complex”, and “gaslighting” in this manner before.
But right now I want to address the specific scenario in which the victim snaps at the abuser. They endure and endure, they have been told that there is nothing to react to, they have been told they overreact to everything, so they are afraid to mention their hurt, and confusion, and cannot acknowledge they are being abused.
The endure so much for so long, they snap. They scream at the abuser. Insult them. Maybe even throw in a low-blow or unfair insult. They may even physically attack, although this is very very uncommon in victims of abuse.
