You are doing the right thing. Get out. Have your phone charged, your meds in zip lock bags inside your purse.
If it was me, there would be not a chance in purgatory that I would be there when he returns. Call Child protective services. She is in danger. You can't leave her but you and her together can get to the police. Do what you have to do. Get a restraining ordet. Go to a women and children's shelter. The police know what to do for you.
This is so complicated because of so many levels. CPS will want names, address, phone numbers of sane, responsible family who can take her in. If there is no one, she may go to a girls home on a temporary basis. She may go into foster care
But her life and yours are in the most extreme danger there could ever possibly be.
My daughter still cries over her best friend who was beaten to death by her husband . He had been released from prison and everything seemed to be going fine.
But he came home one night from work. No one knows exactly what happened. But he has been charged with her death. This woman was a caring, loving friend to my disabled daughter. She was a kind friend to me.
Please, please, please get out of there now with your young teen, and get to the police station. Life is worth living. Don't take any chances. If you must, show your posts in your phone to the officer in charge. This is hard. Be safe. We care about you.
