Maintenance of child and my future

Res Sir, I am 41 and my wife is also 38 and having 10 years old daughter. I am working in private sector and drawing salary 1,00,000/- Pm and my wife is also working is a software consultant and drawing salary 60,0000/- pm. She is living separately since more than 2 months with daughter. I don't even know her address, I tried calling her messaging her but she doesn't respond. Her lawyer is in touch with me and asking me to accept mutual consent divorce. The demands are: 1. She gets the permanent custody of child 2. I can have visitation rights last Sunday every month 3. I should pay 50,000/- pm for child maintenance 4. I should bear the education of child school + college Are these reasonable demands? How much should I really contribute as per law? Our relationship has gone bad because we were staying with her parents for almost 9 years out of 12 years of our marriage. I agreed because her parents were financially broke and I have no parents. I still feel we can mend our relationship but she is not willing to come to any counselling. What can I do?
