As someone who has witnessed domestic violence the reason you can't leave is because he has broke you down to the point were you feel like no one else will ever love you. Well let me tell you this someone will love you and love you right. I went through many relationships were guys took advantage of me and hit me. It took me realizing I desvere better and getting brave to leave those realtionshits as I like to call them. Now I have the greatest guy in the world who treats me like a princess and makes me feel worthy of love. He tells me every day I am good enough. You need to run and I know it is not as easy as it sounds but you need to try. You don't desver what he is putting you through no one does. Also know it is never your fault you don't desver to be hit. I hope I helped.
