Filing divorce to my wife

Dear sir , I got married on 2009. My wife got pregnant within 2 months. After I got a new job i moved from coimbatore to kovilpatti (Tamilnadu). I joined my new job and my wife was with me and always making arguments and fights. 7th month wife's family did the baby shower function and she went to her mother's house. 2010 girl baby was born that time i was in Russia , once i came back me and my family members went to invite her back to our house. She and her family started complaining about me and my job ( I was working as an match factory so my work is day and night , when i joined the new company that time the factory and machine erection was ongoing so i usually came to house late) . Their first compliant - 1. My rented house is in first floor, so their daughter is facing difficulty to get milk and water from ground floor , evertime she need to come down to ground floor. After 3 months of baby birth she did not like to come and stay with me. Then family members talked with her family and then she came to my home that also only 7 months. In between i lost my job due to recession. So i moved back to coimbatore and took a house and using my jewels i gave her and baby in a simple life. Then after i got a job but before itself she went to her family members marriage function . She left my house Jan 2013. Almost 5-6 times with family members and her father friends we arranged so many meetings but everytime she started telling reasons and she is not interested to come and stay with me. She likes to stay with her mom and dad. Even if i ask anything before her answer her family members answering . Now almost more than 3years she is not interested to come and live with me. How i will file the divorce case.
