You have given up doing anything likely to upset her. You adapt your behaviour to what she says she wants. You tried to make agreements or set boundaries. Give Yourself Credit For Everything You Have Tried Never think her violence is your fault. BUT you are not to blame.
All violence has damaging consequences.
Your belief in your worth and your sense of having rights and choices becomes eroded by constant abuse. We all experience stress, trauma, anger, and fear but a violent woman chooses to use violence to control and get her own way. She uses violence deliberately to weaken your choices to act. If you feel scared and unsafe in her presence something is wrong. You are the best judge of how safe you are.
