Divorce under 10(X) and now FIR 498a

Hi, I recently filed for divorce under mental cruelty 10(x) against my wife. She approached the Magistrate and a 498a case has been filed against me and my family members (5 ppl). 1. 498a has been filed in a different state from where I live. Along with 498a, acts 323, 324, 143 & 149 are included. The state/Police station where the FIR is filed is where we last resided before I had dropped my wife back at her parent's house. 2. I have the evidence of proof to confirm no such act was done. She had visited different police stations with the case and they did not file it due to lack of evidence. 3. Even after I dropped her back at her home, she has been texting me asking me to take her back home until I blocked her recently. 4. My first hearing is during the end of September. Question: 1. How can I get the current FIR filed cancelled or deemed false? Because no such event has ever occurred and she is trying to take vengeance due to my divorce petition. 2. Can the I.O close the case at the police station based on the evidence I have? 3. Once the charge sheet is prepared, how can I get this case cancelled in court? 4. In the meantime, can I move the high court for quashing this FIR? If not, when can I move the high court and how long does it take to quash the FIR? 5. Can this FIR 498a support my divorce petition on the ground of cruelty? Thank you. Your help is highly appreciated!
