2 yrs separation, wife not ready to divorce, different states

Married in Nov 2013 in Chennai. In 1 year of marriage - in which the wife traveled multiple times to Japan on company basis. so together stayed with me and my family is 2-3 months. Even I went to Japan for couple of weeks twice i.e. before and after she became pregnant. When she is 7th month pregnant - she went to her mother home promising of returning back when the baby is 3months old. we use to have interaction with her and her family during this period and visit them. Post which she did not come back at all and started telling cock stories that i am not interested. if you want will come stay for 2-3 days and will go to home and giving false allegations on the family and claiming that she will not file for divorce. Now it is been more than 2 years. My job is in Bangalore and stay in Bangalore for more than 10 years won't be in a position to travel to Chennai since I can't take leaves every time else I will loose my job. She is staying in chennai. So can i file divorce from Bangalore and on which grounds, also time taken for receiving the divorce. What is the procedure for filing divorce in Bangalore.
