Husband forcing to take mutual divorce + alcoholic and domestic abuse

My husband and I have been married for almost 5 n half years and we know each other for the past 15 years. When we got married the first physical abuse was on the night of my wedding reception when he slapped me for a very silly reason. Keeping the love apart, he physically abused me at many instances which even I once or twice defended it by pushing him etc. First of all he is a big alcoholic, he just doesn't want to leave alcohol. And all the abuse happens only when be completely drunk. This year in the month of May he was drunk very heavily and beat me up very badly with a slipper, a bat and his bare hands. That time all I had was the option of calling the police to stop him. First I called them and then asked them to give a warning only. Then after some days he fought very badly again with me for some reason and this time he almost took the chappal on my dad who is immobile, that is when I had to call the police again and he was jailed. He was bailed out and my parents and his parents made him understand and then left. He then again started the abuse and drinking. So much so he forced me to get out of the house, and I did. I took another house in the same society and started living there with my 4 year old daughter. Then he started apologizing and such things, at then one day again he started his abuse in that house and again I called the police. This time I only told them to warn them but he got into a tussle with them and then they arrested him. After that I completely refused to stay with him for my own safety. Then he shifted to his parents place and took up a job there. All this while for almost 2.5 years he did not have a job and was at home. Now it is almost 4 months, we again started talking and tried to make things normal but he says that you did wrong with me by putting me in police. Basically after all this he is blaming me and he is not considering or no realisation for what wrong he has done. He says I beat you up and you put me in police it is equal I do not have any regrets. Now he is forcing me to take a mutual divorce. One thing is sure we cannot stay together coz of his mentality. What should I do. As the reality is I cannot stay with such a abusive man. He also keeps scaring me that daughter custody leke to dikha and all of that. What should I do?
