CrPC 125 and 498a

Hello, I was married in May,2018 and the marriage was solemnized on the basis of misrepresentation of facts as my wife is a Bipolar and she was getting treatment for this since 2015. This fact came into my knowledge only in August 2018 as she ran out of medicines that her parents had given to her. I decided to continue the marriage and her treatment as well but she kept on having mild attacks and in Feb'2019 she had a major attack post which I called her parents to take her with them as it was getting difficult for me to take care of her. They came and took her with them (everything happened normally as I had told them that I will come after a month or so to take her back). We went to meet her in Feb'19 and secured a written statement from her father and herself that the fact of her being Bipolar was kept hidden from us and there was no dowry asked for before, during and after the marriage. I also did video recording of this whole conversation. In March'19, I filed suit for annulment of marriage ad to counter this they have filed suits under section CrPC 125 for maintenance of Rs. 30000 per month and also complained against me and my family in Mahila thana. I have all the proofs (what's app messages, pics and a written statement to prove the claims to be false) and have been called by Mahila thana in last week of June'19. My wife is unemployed and has done MSc. My question is: 1. Can she still file an FIR and 498a case be registered against me after I submit all the proofs in Mahila thana? 2. What legal action I can take and how can I get CrPC 125 case quashed? Thanks
