Hello,
First thing that a divorce can not be filed before one year of the marriage.
As of now you can file a suit for judicial separation.
take out the coy of the missing FIR and file a case of divorce later on the ground of mental cruelty.
Also, on the basis of the FIr lodged by you, file an application for dismissal in all the cases filed by her.
You can file the divorce case in Deharadun, and also the judicial separation in Dehradun.
Regards
