They never change

So my soon to be ex. Has been on this path to better him self and fix our marriage. he used to hit and was very aggressive. for over a year after I left and said I wouldn’t come back he swore to change he did till today. I have been not really feeling the relationship anymore after the abuse and him cheating. So today I decided to tell him how I wanted out. I regret it so much he beat the shit out of me... for the first time ever I thought I was going to die I screamed for help and he dragged me by my hair to our laundry and was choking me and putting this really thick blanket over my face and hit my head on the floor. I have never been so afraid in my life. And now I have to figure out how to leave because I’m scared of what he will do if he catches on to my plan. Also I don’t have money our accounts are separate and he is the only one who works. The planning begins. Me and my kids won’t live like this. No one should have to!!!
