See it is better in my advise to give a mutual divorce and ask for alimony from him for you and your children maintenance. See there is no need to get into legal hassels and keep fighting cases neither it is good to be with such abusive person so instead you can give mutual divorce demand huge sum and le=ive peacefully.
if he doenot agree file a case of domestic violence on him for cruelty and ask for maitnenace for you and your kid.
