I spent many years in an abusive marriage. I lost friends who tried to save me. One couple lived in the same house as us and had directed me to a divorce lawyer and I chickened out. They moved out in disgust. An abusive relationship just takes and takes. You just lose and lose. I even volunteered on a DV helpline to try to force myself to leave. When the dawn finally broke over Marblehead it was when I hit bottom. Even though we'd had knockdown, drag out fights for a long time, it was a slap in the face that ended it.
I write about this in the first chapter of my book that I finally realized that no one has the right to put their hands on you NO MATTER WHAT YOU DO OR DO NOT DO.
Abuse is never okay. Its just not. It is possible to leave an abusive situation and lead a happy life.
There is no "doing right "by an abuser. There is only doing right by you.
I don't blame the victim but you get what you put up with. Once I stopped putting up with it, it stopped happening in my life. There is a dysfunctional dance that partners in a DV relationship do and you have to recognize and change your steps in the dance.
Unless and until you put yourself first, you will never break the sick chains of the DV relationship.
You must learn to do right by YOU and you alone. You cannot do right by you AND take care of him and you must never abandon you. NEVER.
