Section 125 maintenance

I got Married on Dated 8th March 22. On 11th of May, There was a small dispute between me and my wife. She started shouting late night 11:00PM and to reduce noise level I put my hand on her mouth and told her that family will listen all this Pls don’t make noise. Next day she went to her Parental Home with her Father. After reaching her home, she didn’t call me back that day and Next day( 15Th May). After waiting for her call for 36 Hrs, I called her and asked to give her phone to her mother. Her mother Blamed me that I chocked her daughter’s Neck. Which is purely false. Later issue was resolved and I bring My wife back after discussion with Family but I lost my faith on her and started recording my private conversation With my wife. After 15 Days, I got to know that she talks to her boyfriend on WTSAPP and after that delete all the records. I confronted her for the same and she admitted that she hide about her Friend and I have This conversation recording in my phone. Next day I left her to Her parental House. Next day Her mother called my sister and discussed this, I have recording of the same. There was no blame of domestic violence in that Phone call recording. After 12 Days she complaint to CAW Cell and After one Month she filed a maintenance Case section 125 With false allegations Of Dowry and Domestic Violence. They Included my Sister name on a certain date, on the same day My sister was admitted in Govt hospital. Also I am having Recording when she ask me to give money to her. Pls suggest how to proceed Further.
