Wife fights a lot leaves home frequently and doesn't come back,

I was married in Nov 2013, it was arranged marriage. My wife doesn't work, I am working. Wife keeps visiting her home, I don't have problems with that, however she doesn't consider my home as her own. Second she keeps complaining about all sort of things, don't talk to me for weeks and weeks, immotionally torturing me. In august 2014 she went home there was no fight. After that she became adamant not to come to me back. We tried all possible ways her parents don't talk in these matter, if they do they don't listen and impose their conditions and say that their girl is not getting good treatment from us, wheras its other way around. In Dec 2014 I underwent a surgery and after leaving hospital we went to her home to request her to come back, due to this she came back. We had a baby in Oct 2016 but she did not change, she talks to me very less, when she does she asks for money to be transfered to her account. I kept giving her some cash whenever I withdrew money. My father underwent a surgery in Dec 2016 and she very rudely said she has to go home. I asked her to stay back but she would not agree, merely to avoid any conflict I agreed but when we were planning surgery she kept saying me she will teach me a lesson once surgery is done. After surgery she came back but again stopped talking to anyone of us. I called her mother to explain the situation to her daughter as my father is not well so she should not do such sort of things but her mother denied when I requested to explain this to her daughter over call my wife asked her mother to pick her from my home and take her along. My father tried talking but she didn't even reply to any requests made by my father, my father became angry and did out of frustration told her that this is not the way and all their family is doing rubbish to us. She created havoc and wanted to go to her parents home we all tried requesting her after 1 day of pursuation she said she will come back. Now she says she will not come and neither divorce me and is asking for money. She also took along our kid. I went to her home to request and take her back but she does so much of drama and says she won't come. I no more intend to live with this monster. She never cares about me whenever I fell sick if she has to go to her home or anywhere else she simply leaves if I object (even if peacefully) she starts a fight and tells us that we don't care about her or her parents. Please suggest what can be done legally.
