How to file a case against girlfriend ?

Hello sir / ma'am I and my girlfriend met in Kota 2013. She was selected in MBBS and I in JEE mains. Our relationship from 2013 till 2020. She used me and wasted my time also. We have visited Delhi and Shimla also. She always forced me for Government job that's why I didn't take placement in my collage. Currently I was preparing for MPPSC examination but I failed in first attempt . Initially she was in favour for marry with me but due to her parents she refused and fight strated between us. So many times she said that I will marry with you and I have that proof in WhatsApp chat. After some time I found that she was sexsully adiicated . She sends her nude pics and masturbations video to me. And after some time she starts sending private pics with other person having sex. She accepted several time in chat that she created a tinder account and going for sex. I was emotionally broke down completely and talked to her father but her father filed a case against me 354d 506 and 509. When I was in police custody she hacked my Gmail and added her number for recovery and reset my all passwords example Facebook . She delated all my video lecture and so may may proof that was against her. But still I have some proof. I have also proof that she so many times she said on WhatsApp that call me or rcv the call . Please guide me how to file case against her.
