My friend has an abusive dad and gets beaten at least once or twice a week. She tries to keep low when her dads there but her dad always finds something to scream and hit her for. He occasionally brings out a knife and threatens to kill her dog. He also makes her go outside to sleep sometimes. They've tried a bunch of ways for him to stop being mental. The dad knows what he does isn't right, but he just doesn't care and he knows they won't tell the police or anyone. Her mom can't divorce with him because she can't earn enough money to take care of my friend and her brother, plus tuition for college in the future. They can't call the hotline for an abusive parents because of this too, so my question is how to prevent this from continuing?
