My husband abscond to uk for study without telling me, with rs 10 lakh of my parents money

My husband and me living separately from past 7 years due to different work place, he was always abusive to me n from past 1.5 years he stopped any physical relationship with me. I started doubting him n recently came to know that he was doing incest with his cousin sister and living with her from past 1.5 year as per neighbours, due to Corona lockdown I didnt get time to go to his place. He took rs 10 lakh from my parents to go abroad, n promised to return. But I told my parents abt all the problems in our relationship so they interrupted. He was abusive n saying to me that he is no more sexually attracted to me, he is not physical satisfied with me n all bad things abt my appearance. I got immensely depressed. He asked me to ask people abt the issues. I did a mistake ,I started talking to some stranger on instagram and he saved me from committed suicide, he was married man from USA . I chatted with him abt all my problems...n yes I did talk rubbish tooo. I deleted my chats everytime and he too, but I do not know how, he got all my chats, I think he has put some spy app in my phone... I apologized to him regarding this, n went his home to apologize . There they broke my phone and abused me verbally n physically n next day in the morning he told me to go back. We have taken loans together ,home loan and car loans. Flat is on his name but loan on both of us name and car loan on my name. Now he absconded to UK with all my parents money, leaving all loan liabilities on me, n leaving my son responsibility on me. I am working in govt job.i asked him to end marriage, he is not ready for even that. He threatening me with that chats to show to everyone n that infidel.i asked him to divorce me then but he just absconded.i told my parents that yes I chatted with someone. N trust me during my whole marriage I never even talked to any men casually, but he pushed me in to this n I chatted with someone. N although those chats are prove to my infidelity but also proof of of what he did to me through all those years. Kindly guide , I dont hv those chats as I deleted my account but he has.
