3. Once you have been physically abused, do not be alone with the abuser again. This is another reason to tell everyone you know. You either need a place to go, or someone (perhaps several people) to stay with you until you are safe. You may also need financial help. There are shelters you can go to which will keep you safe. Call a Domestic Violence hotline to find a shelter.
4. If you are hit, call the police (911). They respond much better now than they used to, and the law is now on your side. When they come, press charges. Do not make excuses to yourself or anyone else. If your abuser gets away with it even once, he or she will get more abusive. Do not listen to pleas for sympathy, understanding or forgiveness. You can forgive the abuser after he or she has gotten help, and only after you and your children are safe.
5. If injured, get medical help. Tell the doctors and nurses the truth about how it happened.
6. File a restraining order, or a Protection from Violence order. Volunteers at the police department will help you fill it out. With a restraining order, you can call the police as soon as the abuser gets close to you or your home. Without one, the police need evidence of the abuse to arrest anyone.
7. Attend Al-Anon meetings. You will learn a lot of good information that will help you avoid being someone else's victim. For information: http://www.al-anon.org/
It Ends With You: Grow Up and Out of Dysfunction has good information about taking good care of yourself.
