Breach of trust and promise & cheating

A woman has cheated me after having a relationship for 3 years and every time assured to marry me and wait until she gets divorced and I snubbed my parents decision for looking for a girl for me to marry as I was already 30 years then and now 33, I left my native place and settled in Bangalore just for her sake living at home that I am working in a company. And in all the three years most of the conversations has happened via texting and whats app where I repeatedly keep asking are u sure that you are committed to me or is this just a fling. She also told that its was a love marriage and later filed for divorce, but her parents are not supporting her and pushed her to stay for some more time until they come back from Dubai. The girl has confessed the biggest mistake I did agree what my parents told and made a kid was the biggest mistake, and he also said how she gets emotionally abused at her inlaws place and she has nobody to support or nowhere to go. She was working in MNC company but later took LOA from the company giving false reasons for her kids ortho ailment and worked with me on building a website and used to stay with me from morning 10 o clock till evening 8 o clock and then go home as she was mentally tortured and humiliated by her in-laws. As she convinced me with evidence everything in texting, and also I made her dad an introduction broker in Dubai and that commission in $ used to come to her dads account every month, and he transferred that money to her as she had to pay monthly education loan as she is on LOA she won't get salary and cannot repay the loan, it will be hard for her survival. To say am a top down technical analyst financial markets word wide dedicated and sacrificed my entire teenage days and early or late 20's and focused on my profession of achieving something and also my maternal uncle is a central cabinet minister , and it was hard to tell them that I will be marrying a divorced woman with a kid and in the society it has an impact on their image. but still knowing and believing the plight of the girl who has no support of her parents and in-laws and husband treat her badly even her relatives when to visit her they treat badly which melted my heart and came to Bangalore just for her moral support and she wanted to marry me, and finally she found a right person, and i sacrificed other things and was in Bangalore in a apartment just for her sake.. and frequently used to ask her before it's too late please tell me are you really committed or this is just a fling, and the only good thing I had is I have all the conversations with her on what's app and to assure me repeatedly sent her husband SMS in front of me regarding divorce and her relationship and also she has told many times that once she did the biggest mistake agreeing to her parents but this time I have my own mind and I assure you she and me her kid of 2.5 years will marry me and move out from there.. And also as her husband had an ego problem and not being responsible man enough to perform his duties and right from day 1 the first birthday of the kid i made sure to arrange all the requisite to host a birthday party by herself without husbands involvement, after few days she started getting the kid, and it got very much attached to me and we were taking her and playing in the park and malls assuming this is my family and my kid, in my past I never had a relationship for 9 years and this person was my second one - and there are so many data available from day 1 up to end how she used to say if you weren't there in Bangalore then I don't know where I would had been. And sometimes after 2 years i told her my mom sent keeping well i need to go back to my place for few days and every time she started crying and emotionally melted me that if i go of they will be abandoned, and everytime i changed my mind and stayed in Mangalore - as i came to know her parents and herself are not in a good relationship hence I tried my best to make peace between them by counseling her how she has to talk, and what to say every word and gave some wise thoughts and all along she used to ask me what to reply for her fathers and mothers mobile as she hates them and can't talk sweetly with them, and there are messages and times I asked her why did u fall in love with me so much as she said in words and I always get the best out of her, and we are soulmates. and i have also told why do u think I am a nice and kind person when myself was telling I am like a sociopath and some people talk bad about me, and it went on for 3 years, all of a sudden some day she started avoiding me and blocking my calls and ,messages and despite making repeated attempts to contact her or her dad just make sure she will be safe there no matter if she has a change of heart but as I knew the details about their internal relationship I assumed it's better me making sure than abandoning her to their mercy as I have screen shots of everything of her plight if nobody supports her, When I tried to contact her dad he started blocking my calls as well as emails which too got blocked. Then I remembered something which happened a 6 months ago, her cousin and ex-boyfriend had started contacting her via SMS and asking her why did u cheat me I want a reason, please tell me and he looks like psyche t00 - I told her why don't you say your parents about this or did u talk to her husband she said I am not saying because my parents will blame her for having a relationship with that person was her mistake and them don't interfere. So i took matter into my own hands and talked to that person and made him stop stalking her once for all and never even tried to ask that person what cheat, cause i blindly believed in her and lied my parents I am working and also pushed the marriage topic whenever they say it's high time, As the female had assured so much I literally believed she is the one and I am gonna marry her sooner or later as she is committed to me and age doesn't matter as she is the one. ' Today I had been to their place fo one last time and asked her husband to pick my call and talk or say your wife to speak to and it will be over why do u make me come repeatedly and keep trying to contact you - but today he didn't even allow me inside gate and was fixing CCTV cameras with some motive and take legal action so even she is included in that, and she is not in any trouble, and she is cool, so now I just want to see any legal ways to file a PCR of cheating abetment of suicide or just give a complaint in local station and make her come there from the house sending cops so it will all be over. She and her husband deserve that, and that's enough for me. I know Indian laws guys usually don't get justice, but at least I want her to visit court every now and then and take their peace of mind and happiness by making them attending court. I contacted a couple of cops today and couldn't tell the whole story, but I told them I have a message and she was working for me, and she had filed for divorce, and she doest have her parents support now we just want to make sure she is safe there. hence the cops gave me an idea of filing a writ petition via court and submitted to the nearest station, and they will enquire their husband and ask where is she have you killed or what. But I couldn't tell them what I wanted rather a guidance was to how to go by it. And I have made up my mind that they should be taught a lesson for their arrogance and ego as many times she herself told me they way you treat may say volumes about you - one good thing is we have each and every single data stored of three years in the I cloud backup. She has also violated the norms of an MNC company by taking a false leave based on medical grounds giving a reason of her baby and also had edited her ITR and send it to her husband as he was asking her in suspiciously. So how can I start the process taking the first step ASAP, and the evidence I have is very genuine solid, and the whole story is there.
