I am going to just repeat what everyone else has said. Get out of that house. Take Alex with you and go to a shelter or to your family. No person should ever strike their spouse for any reason. From what I understand it will just get worse until you and your son are in severe danger. Your T is right, you have to make the dicision to get yourself out of this situation. I know you love your husband but please love yourself and your son more. You deserve to be treated well. That has to start with yourself. You have to make sure that you get what you need because no one else will...though your T is trying. So PLEASE PLEASE PLEASE get out of there and get somewhere safe.
Worried Sick About You,
Carrie
