Her own needs goes always than mine

Hello All, I found this platforrm while searching online for my maritial issue. I got married on Feb 5th, my wife travelled to USA on March 2nd or 3rd for her work (this was discussed with us before marriage and me,my family had agreed since i am a career oriented). My wife will be good wife if her mood is good, she takescare of me very well (she stayed in our home for 4-5 days in feb and stayed around 20 days in december 2020). My parents had provided the front postion of their site to my sister (this was discussed to me long back before giving the site has gift deed to my sister though it is a gift deed my sister had cleared off 8-10 lakhs loan for this gift,i had agreed since my sister has helped my family a lot during my education period and even now whenever i need financial support she is the first person stand in front of everyone). Coming to my sister family, my brother in law is automobile engineer and he often travels to other states for his work, my sister has 2 children one is 10 years and another 2 years old. My parents are the only source for taking care on my nephew and niece since she is also working. Before marriage we have clearly mentioned about this to wife's family and to my wife( i have proof in whatsapp chat). Now she is demanding a seperate house since my sister is in front of home and children will be always stay in our home. I,my parents and my sister tried convincing her that after she comes back to india my sister will not come to my home instead my parents will go there to look after the children. My wife didnt agreed and insulted me by saying my house doesnt looks like a house ( its a old home constructed by my dad's hard earned money and renovated to included 2 bedroom from my hard earned money). After all this my parents with pain insisted me to go seperate to live with her happily as her wish. Now she is giving me torture, If me and she moves to different people will point to her saying she had broke the home when i asked her to stay together in the same house she replies saying i cant kill my happiness because of your and your family. I always say to her is do as you wish, on [deleted] she told she cant do both and she is ready to give me divorce i said do as you wish. today i.e. [deleted], her mom is calling me from past 2 days but i didnt pick her call because for all this ruckus she is also responsible, she fills in all bull shit in my wifes head and later she plays nothing she did. Taking this situation my wife is keeps on calling me and torturing me saying she will die (this will happen for all fights always her mom knows all about this). My parents,sister and myself are not at all having peace in mind, i dont know how to resolve this issue. Please help in providing some inputs or law point to teach her the value of family.
