How to proceed further to get divorce from husband .

I am five years into marriage with a son two years old , My husband is narrow minded , drinker, abuser , always gets doubt on me without reason and then abuse me , some time I thought he has a physiological problem as after sometime he became normal too but again acts as same as abuser, also their family members doesn't support me , he rarely earn continuesly , and doesn't give monetary support to me to run the house, he often beaten me and abused . Earlier I have tried him to have a lesson , not coming home from July 2018 to april 2019 for 8 months but there on he and his family members apologized and requested me to return ensuring that it will not happen again in 2019 april, but after few months he started again doing so. So now last month I came to my parents house and didn't returned and denied to return . Now what I can do further to have a easy go to have divorce from him and monetary support from him. Can he also file a counter case on me , and how. I haven't filed or complained about him in any legal forum earlier. Also I have some audio recording of his father having apologize and accepting his mistakes, some measges of him having apologize for what he did.
