How to get out of false DVC and 125 case?

I had married a girl and after marriage came to know about my wife's illicit relationships from her chat. I immediately informed her parents and they took her with them. They then alleged me of causing mental trauma to her and filed DVC and 125 case against me. I did not hit the girl even once and they have also not claimed that in their DVC case. In the same period, I also took help from my lawyer and filed a case under section 12-C for marriage voidability and under section 420 for falsely getting their daughter married to me. Before marriage I had asked the girl about any affairs and she replied negative. After marriage when everything came to light, she confessed to me on video. I also have call recordings where she agreed to have such said illicit physical relationships. I also have her chat screenshots with me. Her family has falsely claimed of huge dowry and asked me for huge maintenance and my father's house for her residence purpose. She currently stays with her father. Since she had this degenerate life before marriage and has ruined my life and reputation, I do not wish to spend a penny on her and also wish to get out of this marriage as quick as possible. Please help me how can I safeguard my money/ property and teach her a proper lesson.
