Harassment by wife

My wife started creating issues from the day of marriage.Beat me in the very 3rd month of marriage while she was 3 mnths pregnant with twins by then.Always created issues,argues with me to go to her home town.When she was 3 mnths pregnant though doctor strictly told not to travel she made a very big issue by packing her bags after I went to office,when asked not to go got on to the road and made a big scene.Most of the time stayed at her moms place only during and after pregnancy just coming to my place hardly for 1 month in between that too only after I literally begged her.After my kids turned 5 mnths came to Hyd along with her mother only on condition that I stay separately from my mother.She doesn't take care of kids properly, literally used to keep diapers with potty for hours together without changing as she did not like doing all those things. I took a house near my mom's place so my kids can get her help.She never cooked during her mothers 1 month stay and always used to harass and argue with me before leaving to office, after reaching office on calls and after coming home as well.Neither did she took care of her mother who has multiple medical issues including sugar, nor my kids,nor myself and our health's deteriorated,my mother who is an working woman with severe arthritis used to cook and send food for all of us.Her mother health condition became bad and was sent to their village where she expired. Now my wife blames my family stating my family killed her.When she was sent to home town for her mother's funeral she again rejected to come back. After a month she kept a new condition that I should shift to a completely new area near to my office in Kukatpally that too searched by their family members.Also,that I should not contact my mother,sister or brother completely.When I said my finance will not be sufficient to manage such huge rents she brought her 3 sisters along with their husbands,a generalist and a ACP (may be retired) injecting all -Ve thought s in their mind and to go ahead and file a case with Woman's Cell against me and my family. After they met us and initial arguments they came to a conclusion that it is not my fault but my wife fault that she is very rude and harsh in her language,behavior and thoughts.That she is still immature and stubborn.They asked me to move to a house near office for a yr or 2 so her mindset can change and i agreed for that.After visiting a house searched by their family memebres in Kukatpally which is high in rent is forcing me to finalize same,when i said my salary will not be sufficient she now started asking for my salary and wants to handover same.She is abusing me and my family very badly,though they have been very supportive as my sister has been through a lot of domestic violence but very never registered any case. My sister's sister in law is in contact with my wife secretly even before my marriage and provocating her, managing contats with neighbours for our house update. Pls suggest
