Wife is demanding to get seperated from Family

I got married 4 months back to my wife (Single Child). Before marriage she use to act good and her parents were also acted to be good. 2 months ago when i was at office(Travelled out station) she was at home with my parents. Purposefully she asked my mother about purchasing gold and clothes to my wife and tried to create quarrel situation with my mother. My mother didn't say anything in a harsh way or didn't even scold her. After a while, she called her parents to come and created a quarrel situation at home and their parents asked her to leave with them during the same time. I called my in law and requested to not to create nuisance at home even then in laws were shouting against my parents. Father in law even scolded me with bad words. Then i said i will be dropping her the next day morning at home because it was already 11 PM in the night. They returned back home and next day when i reached home in the morning she was talking to her mother on phone(where she didn't even make a call to me even once). Then i took her and dropped at their home and returned back. From then there is no call back or message from her. Elders decided to speak to her and when they ask my wife is demanding to have a separate family and where she don't come to my house and either i should go to their home. All the family spendings should be taken care by me and she want's her income to be kept with her(earning equally). Help me in this how can i bring her back to my house where i need to take care of my parents too as they are physically ill with heart problem and knee problems. (Maids are there at home for all the cleaning activities)
