Alimony Amount

Case Summary: 1. After my parents visit to my place, my wife quarreled and she left home in Sep 2014. Defamed me and my parents among our friends and relatives. 2. Unable to bear her attitude, I filed Judicial Separation in Dec 2014. 3. She responded with 498a against me and my parents in Jan 2015. We contested the case and were acquitted in Dec 2018 stating, the prosecution was unable to prove the case and marked as "Mistake of Facts". 4. She is currently receiving maintenance of 7000 rupees per month since March 2015. 5. At the time of marriage Jan 2014, she was working in a bank. She is equally qualified as me and is a engineering graduate. Though she works secretly in some private firm, she claims to be not working in the court and receives maintenance. I'm trying my best to gather some evidence about her current employment. 6. The RCR case filed by her was granted in her favor in Aug 2018. I have applied for review of the RCR case in High Court as of now. In this context I have following question. 1. Can I file any criminal case or defamation case against her even if the judgment of 498a does not mark it as False case ? There were many false allegations made against me and my parent. 2. Will the divorce be granted based on mental cruelty incurred due to the 498a case? She also had tried to commit suicide by drinking shampoo for which I have audio recording and medical proof. 3. Since my salary is around 3 Lakhs per month, what might be the worst case alimony granted to her? After 5 years of continuous mental torture, anxiety and trauma caused due to her false allegations and multiple cases, I cannot imagine a happy and peaceful wedded life with her. Hence I tried to talk to her for mutual divorce, but she is not interested. She is very stubborn and claims to deny divorce even if I have to approach supreme court. Please advice me about the next step I must take and also the above queries. Thank You
