Too bad you couldn't move out with another family member. Have you asked? Maybe if your old enough you could move out on your own. Do what is best for you!! There are alot of places that will help victiums get out of the situation they are in. There are support groups everywhere for survivors. I recomend getting in a support group if you can they are 95 percent of the time free. If you can't get out the same house that he will be living in. Then anytime that he seems like hes angry or drunk go in your room and lock the door. Make sure you have a phone with you just incase he gets in. Be safe and do what is best for you. Take care!!
