My husband is short tempered he hit Me many times Till date.within one month of marriage he hit me twice... bt somehow i managed since mine was luv marriage..bt then frequency of hitting increases .. And in december 17 he told me leave this house because he already filed for divorce..i felt so helpless and i left his home In feb 18 leaving all my belongings in that house and start living in pg in delhi.. i never asked for any money or any kind of help..i concentrate on my carreer and phd preparations.. but now after 8 months i many get calls from him and his family as his sister marriage is fixed in december18 and he wants to patchup so i met him in oct 18 and discuss issues .he then ask me to meet his family members and sort out the Issues with them also..so i met them in 1 November 18 night but this time my sister-in-law and mother-in-law abuses me and hit me..she threatened me that she will kill me.. i locked myself in one room and asked my roommate to call the police..when police came They also harrass me “ki mahilaye bhi lockup me jaati hai aajkal” and did nothing.. and i came yo my pg that night only I called the Women helpine today 2 nov18 and tell the issues to mahila ayog..she helped me and i register a complaint My husband also complainEd against me that i hit his sister. Plz suggest legal implications in this matter and oblige. I will b very grateful to you
