Police Complaint by wife family

Hi, I got married on 25.11.2018 and within a period of 45 days she left home and did not came back, even after following with the family member and relative she was giving false allegation about me and my family like not giving food etc. so we kept patient for some time. but recently on Oct-2020 she file a complaint that mentioning dowry demanding, impotent in women's policy station and we want divorce they are demanding . we have attended the police complaint along with our lawyer,15 lakhs rupees when no action was taken by women police station they again gave same complaint to ASP office and requested them to take action after meeting the police personnel they insisted us to take a impotency test to prove wrong. I believe that point of impotency is invalid. Now after all this happening i would like to go for divorce please suggest me the best possible way for getting the divorce we are separately living for 2 years (the Initial police complain was raised by wife after 20 months of leaving the home) I stay at Mumbai and my wife is from my native Tamil Nadu the police complain was given at my native. Can I apply for divorce from Mumbai. how long the divorce case will proceed
