Mutual Consent Divorce Terms & Conditions

Hi, All the cases started in 2014 by my wife filing a maintenance amount case for child. It was later disposed in June 2015. In Nov 2015 she filed a false case demanding monetary and gold items, which were then held by her long back. In Jan 2016, I filed divorce case and recently in Aug 2017, I filed custodianship for child. In Jan 2017 she filed another one demanding enhancement of child maintenance amount. All other cases except the very first one are still running. Suddenly in Sept 2017 sometime out of blue, her lawyer came up with an 'offer' kind of thing that they are ready to withdraw all the cases and ready for filing the mutual petition - upon one demand. I will not have access to child, I will not be entitled to see her or not allowed to file custody in future or anytime. I like to get an advice on this. I am okay with the mutual petition terms except this. I like to have access to child, want to see my daughter, want to know her etc etc. Please suggest me how I can handle this situation. On one side, if I agree I will get rid of all pending court cases and on other side I have to compromise for the child. Lot of mediation and conselling were done without any outcome. Thanks in advance.
