False maintenance case and criminal cases filed by my wife on me and my family

I am currently working as a faculty in tutorials and as a home tutor in Bangalore. I got married in April 2016. My wife left me on 7th October, 2017 with her mother and sister-in-law. I have called her many times to return, but she didn't accept to return (It happened many times in ONE and Half year of our marriage life). So, I waited up to one month and in November I sent a Lawyer notice. But she didn't respond and after 20 days I lodged a case in Bangalore Family court. My wife lodged a false complaint on us in her hometown in Andhra Pradesh. So me and my family went on 17th December, 2017. We told to SI that we have already filed a case on her in Bangalore Family court (because she left me so many times and blackmails me). Even SI also came to know about me and my family. We informed him to send us (me & my wife) to MEDIATION/COUNCELLING center. While leaving he told us that my wife was ready to lodge a false FIR on all of my family. Then my lawyer asked him about the situation that how could he can lodge a FIR on this issue, because we already lodged a case in Bangalore Family Court. Within 3 days i.e, on 21st December, 2017 my wife lodged a false FIR on all of us(Parents and my brother). Sections are: 498-A, 506 r/w, 34 IPC, 3,4 DPA, 420 IPC After reading that FIR me and my parents shocked... she has fabricated the case to imply the above all sections. Now she filed a Maintainence case on me in March 2018....(30000 per month) Now we appointed one lawyer in her hometown... We went for first hearing. Next hearing will be in the next month.... I have given all the case details which I filed in Bangalore... Even I told him about the evidences which I have(audio, video recordings and about first 3 meetings in the presence of our relatives etc.) This lawyer told us....... 1. that this case will not stand for so many days and mostly the case will become quash 2. if you want divorce.... then compulsory you have to give maintenance...(even it is a false case also) My lawyer suggest me to do settlement with her by paying permanent alimony maintenance if I want divorce... Questions:: 1... If I submit these evidences before judge.... can the court still award her maintenance OR the court gives her punishment by cancelling all cases.... 2... what kind of evidences should I submit for this case (rather than above evidences) 3... if court confirms it as a false case based on my evidence... then can I go through prejury and defamation case on my wife and in-laws...
