Muslim Marriage act and FIR

Hello Sir/Madam, We are Muslim and our marriage happened on Feb 2017. I failed petition due to torture from my wife, she keeps lies and tries to threatened me with some audios which has been recorded during our fights and she demands to go get seperate from my parents to stop. We moved for 4 months out but still the problem continues with elders advice we back to our house, during that time she torture me writing sucide letters (I have copy). She was pregnant and she left home during 3 months , even doctor advice don't go and send notice that she is safe and wish to stay with her family till delivery date and don't force to come. I approached my hajji to get back her , she didn't accept and I sent 1st talaq letter but she refused stating all reasons are false allocation all these discussions are in wtitten proof. Now the issue is..... After lost of my baby I failed divorce In court under Muslim Marriage act (DVOP) after the notice issued from court she failed FIR 498A and Dowry case against me and my family. Meanwhile she sent lawyer notice demanding 20 lakh cash and monthly maintenance as 20k but she is earning in IT firm. I already had one 498A when I sent talaq notice , that is closed by committee members in court since lack of evidence from girl side. My question is... 1. Will I get divorce easily , she is very stubborn and she never mind to go any extereme. I.e mutual possibility is 0% 2. How to come out from this FIR, what is the evidence I need to submit. 3. How to safeguard my family from this FIR and complaint in future because it's 3rd complaint in 7 months. Thanks, Karim
