Section 125 Followed by 498a - False Cases

Hi, I got married in Feb 2016 and within a week of getting married my wife started beating up my mom (a widow) at home. when we said this to my in-laws they started threatening us with dire consequences. her cruelty towards my mother grew by the day and one fine day I had to go and file a complaint against my wife in nearby police station (non-cognizable offence complaint). Post this the police visited us and advised my wife to behave properly. The next day she called her brother and secretely ran away from our home and did not even answer our phones. after waiting for 3-4 days and trying to reach her I filed a missing report in the SP office. We did not hear from my wife for next 5 months and one fine day got a notice from court for section 125. I filed a annullment petition at my side as it was not even 1 year of marriage. a few days ago we got a notice for section 498a in the name of all my immediate family members which is totally based on false accusations and has no truth in it. I am at a loss in what to do. Kindly advise.
