Lois, please do all you can to stay safe and keep your daughter safe. And if you haven't already done so, please contact your local victims' services agency. They can help connect you with counselling services and other supports. You may already be getting counselling, but it is essential to help you learn how to escape the victim mentality that keeps so many women prisoner. I've been through it myself, although my ex was not a JW. But even after he ripped chunks of hair out and blackened my face (in front of my children), the elders told me staying in the marriage was the right thing to do.
When you stay in an abusive relationship, your children are also in danger of developing the same victim-think which can lead to the same thing down the road for them. Two of my daughters have recently escaped highly abusive relationships, but not before sustaining damage. Gaining self-insight and understanding into how abusers set up their victims and keep them terrorized is what finally helped me regain my self-esteem, and that knowledge will help keep you safe in the long run.
