You need to leave as soon as possible. Don't involve your grandaughter in the development of your leaving plans. Children are innocent and honest and frequently will give away confidences by accident. If your husband is violent, this may then inadvertently involve her in some kind of ugly situation. Only let her know your plans once you are ready. In the meantime, she is your care of duty and you must be with her at all times to protect her.

Have you inquired if there is a women's shelter in your area? This is often the best place for women and children to move to when they first leave a violent situation. The shelter will have access to sympathetic and informed people who will help you to start a new life. I would strongly recommend that even if you don't think you need the shelter, that you at least make contact with one and establish how to call on them if you are suddennly in a positon where you need them urgently, or there is an emergency. It's critical that you know of some place to go if you need one. My heart goes out to you both.
