My wife has left me and is now not returning.

My brother was lost in an accident 2 years back, so my parents want me to settle fast. So they hurriedly married me. They rejected earlier proposals who needed time for marriage. We were married on 5th march 2017. After which when I was coming to chennai, even her mother came along with her. And she fought with me daily, and her mother abused daily and my family whenever they called her. Once when I was crying while talking to my parents, they took flight from kolkata. And after booking of their ticket she started saying she is in pain, but at that time no doctors were available to cure in any nearby hospital. When I asked her to come with me to Apollo, she denied to come. And later her father called me and requested to send her back, and listening to his request I sent both wife and mother in law. But she never went to her father. She went to her sister's home, even after knowing that I have doubt over affairs between her sister's husband and her. She went to hospital there, saying me that it was critical. But her father never went to visit her. Now she has gone back to her father and her father is not ready to send her back inspite my father has visited her father. He says, she will open a firm and then only she will go. My complete family is suffering now. I have railway PNR number of both side of journey, where her mother's name was also mentioned. How can I bring her back now and avoid this kind of situations in future? They are threatening of doing fake cases but is never saying on phone that those are fake. Eg: She sent sms saying you want to kill me so that you can live with your girlfriend in Live-In. (I don't have girlfriend). I have never raised my hand on her.
