Regarding Maintenance and Divorce

I got married in 2009 and had been living with my wife till 2018. My wife happens to be a teacher in a reputed public school and has been working there for the last 14 years. We have no children. She is still continuing her job there. In Feb 2018, she suddenly deserted me and started to stay at her home with her parents. In Feb 2019, she filed a Maintenance Case against me asking me to pay her a maintenance amount inspite of the fact that she herself is earning. In between she asked me to settle for a Mutual Divorce which I agreed to but she didn't file for it. Till now there have been 3 hearings in the Court for the Maintenance Case and the next hearing is scheduled in Feb 2021. I have few questions - 1) Is she entitled to get a Interim Maintenance since she is currently employed ? 2) If yes, then what will be the amount ? 3) In case if I initiate the divorce first, then what will be the advantages and the disadvantages ? 4) How much time will it take to get a divorce ? 5) If divorce is granted, then do I have to pay Alimony to my wife ? If yes, then what will be the amount ? 6) With the Maintenance case going on, is it advisable to file a divorce case ? 7) In case if I initiate the divorce, then is it expected that she will file few cases against me in retaliation ? 8) I am planning to go abroad in 2022 for my research. Is it possible to go abroad when case is going on in India ? Please let me know.
