Wife asking to either buy or transfer parents house on her name

Dear All, I got married 4 years ago. After 1 year of marriage she started asking me to buy plot or flat on her name. So i filled HUDA and DDA flats on her name only, but not lucky enough to get name in lottery. So in end of 2013 we opened an account in Y bank on joint name (me being 1st owner) and started to transfer my savings and money left from salary to Y bank. Then she felt ill and after many test she was diagnosed with TB. So i started medication, doctor didn't prescribed some vitamins due to that her health started doctorate. So i took her to max hospital where vitamins deficiency was diagnosed so i started same. In end of year 2014 she went her home saying that you people don't treat me well as my mother went to my sister house for her care as she was pregnent. Also during this in 2015 feb she opened an separate account in Z bank on her name and started transferring money from Ybank (joint onwer). I asked her the reason, for which she say u don't trust me. And even we have small fights for that mony tansfers. In 2016 i asked her for mony to get some repair work on house. She started having fights on other topics and went back to her home. When i went to her home to bring her back, i came to know that her mother already know everything abt the money and asked me to take half money from my father for repairs. The discussion was finished without any conclusion and she came back with me. Then she again demanded house and property. In jan she took the jewelry given by my father, (the jewelery given by her father was already taken by her in 2015). Then we have a fight and i stopped talking to her. In feb 2017 we have a fight for almera and she went back to her house so in march her parents with some relatives came to our house and asked her to return money to Y bank and also returned jewelry (only our side). After just 5 days she asked me to buy her a car and she called her brother due to fight. Now in end of march i asked her to go back to her house. After all this her relatives and brother is giving us threats of false cases of dowry, misbehaving, and saying that my family used to beat her. Now its 2 months she is at her home. Can she fill a case of domestic violence. What should i do now.
