Married for 3 months, no child, 3 Talaq notices sent and acknowledged. Girl filed case under "

Hello lawyers! I am in a difficult spot. I am from Tamil Nadu. I was married in June 2020 to a girl from Bangalore. As per faith, we DID NOT WANT, NOR WE COLLECTED EVEN ₹1 in dowry. We have also given her Mahar of ₹7 lakh. The girl's family have wanted to exit the marriage for a week into the marriage. The girl wasn't interested in the marriage. The girl's family didn't invite anyone for their marriage and kept the wedding a secret. During the marriage, the girl has been defaming me and revealing personal details to relatives. Later, they had told me to send the 3 Talaq notices. Otherwise, they would defame me through the media. They have received and acknowledged the 3 Talaq notices. Just before the third notice, the girl has filed a case against me in Bangalore under Sec 26 R/w O-VII R01 of CPC R/w Sec 2(viii) of Dissolution of Muslim Marriage Act. The girl is 22. Her father is demanding ₹37,00,000 for being married for less than 90 days. I have chats and other proof that I was a good husband to her. I would like to know what the implications of the suit are? Thank you.
