Issues during ongoing divorce proceeding

Wife filed false divorce case after 20 months of marriage. I contested the divorce. Its been more than 1 year of separation and more than 1 year since wife filed for divorce. Divorce case is currently ongoing (just had the evidence submission by wife). I recently started dating a girl from office for 3 months. This girl is already divorced. But we broke up. Now this girl plans to join forces with my wife against me. Below are my questions : Q1) What additional legal case be brought against me for this affair ? This will NOT be adultery as per IPC 497. Q2) Since the divorce case does not mention about the affair till evidence submission stage by my wife, can this be added later ? Q3) Since this affair happened just 3 months back, after more than 1 year of separation, and 1 year after the divorce proceedings were filed by my wife, what all issues can occur ? Will this be considered valid, and help my wife\'s case ? Q4) Will this have any implications on other case like 498-A (which my wife also filed as false case)
