You can take the following steps:

The facts, as posted, are confused. For instance, what is the relevance of your mother-in-law's demise which happened years before your marriage. The inconsistent and disjointed facts suggests that you are staying away from the husband without convincing  justification.

Please post concise facts.

Before taking any legal remedy as advised by expert mr. T Kalaiselvan, which I fully agree and appreciate his acumen yet I feel you must prefer to explore possiblity of amicable settlement with your husband and in-laws with the help of relative(s) / elders / respectable persons in the society / friends and/ or marriage counsellor and save matrimonial institution.

Sir my mother in law died in year 2006 as she saw my father in law with my sister in law (Jethani) now everything is in her control. My family was not knowing anything about this. As I stayed  for two years in sasuraal I came to know little bit . My elder sister in law tortured me a lot. She was willing from day 1 that I should leave my matrimonial house and go to my parents house. But I stayed too strong that as I got married I will not leave from here but all limit was crossed.. openly I was challenged by my brother in law in front of my husband k muuh biggad k rakh dunga kahinkaa nhi chodunga.. I got afraid and after the false case of dowry domestic violence by my younger brother in law and sister in law in year 2016 I was feeling like a criminal than I left house got worried they can do anything I got mentally disturbed my parents supported me and I stayed back to my parents home from 2016 till date. My husband was also showing that he is helpless can't utter a single word . I have done 1 mistake that I have not listened to my parents to counter file case against my husband and in laws family. Neither I have filed case for maanhaani as I was willing to live with my husband and daughter happily I don't want to get involved in all this case and all. But my husband showed me true colours of him. Now he was coming in between to Mumbai till year 2018 before my 2nd daughter birth .As I gave birth to 2nd daughter in year 2018 he didn't turned back. My case got quashed in year 2017. My husband with my elder brother in law calling late night and telling Mujhe free karde my elder brother in law was shouting and sail le alimony aur talak de. He used abuse words with my mom. This was arrange marriage and my family trust the person who was between this marriage. My father in law says to my relatives hum ladle k dusre shaadi karenge.. I waited for long but not understanding now so I want to take a stand for my 2 daughter. My elder daughter is 10 years old now she is violent not able to focus on studies she missed her father but she knows the fact of life so I want to make her so strong not looser. My younger daughter don't know the meaning of father as she has not seen him. Sir my daughter are growing up I want to remove all dark clouds from their life. They should not feel shame that they are leaving in Nana nani house. Sir I am working and earningapprox 40000 but very difficult for me to manage with 2 daughter in Mumbai in as it was mentioned for claim..Before marriage my husband was having affair from last 5 years I ignored everything as I was willing to start new life . He also supported me only for showcase nothing was original. He is showing true colours now.
