Mutual Divorce rules

Hi, My wife is planning to get divorce mutually. We have been married for over 6 years. We are living separately since last 2 months. Me and my family members are trying to call her back on daily basis. But she is not coming back at all and saying that talk to my dad how to get divorced immediately. She is saying that I don't want to come back now as I am not feeling comfortable with you. With 'N' numbers of allegations, like Mann nahi Mil rahe etc. I went to met her to bring her back home, but she didn't agreed upon. Her father said that we need to proceed with the mutual divorce, I said OK. Now they asking for 13 lakhs for marriage expense. I am almost job less since last 1 year with no savings, My wife works as a government contractor employee. However, they never spent this amount. Do I need to pay now their marriage expenses etc. Since I do not have own money, can they demand from my family also, in such case. will it be a liability for me or for my family. also they are asking me to show that we are living separately since last 1 year, which I do not want. Can I demand for alimony/maintenance monthly?
