Wife left home past 6 months back along with kid and no contact since then.. What next?

I am from small town now works in Hyderabad since 15 years, married 10 years ago kid of 6 years old. I am from middle class family background living with Parents ( 60 + years of age). Wife was working earlier before the marriage and it was understood wife will continue to work after the marriage also to support the family. She worked as HR earlier (PG holder) but after the marriage she never showed any interest going for job. She is from financially well settled family in Hyderabad, both her sisters are doctors and her brother works in a reputed company in Hyderabad. My wife's sisters are married to a well off families. My wife and her family never treats my parents well always talks low about my financial status.. trying taunt always and judge my family status and my earning capabilities with useless comparisons. Lot lot of arguments happened between me and my wife earlier as well over this but she seems to be never bothered, always respects and support their side.. She always busy on phone with online movies, whatsup, face book... along with relatives. Her kid is her world! Few months backs after a big fight over above issues, I became so frustrated and shouted on her. And she left the house with kid and not in contact since 5 months.. left by taking most of her belongings. She was fully persuaded and motivated by her family members to do so. One Thing was clear for me that - Neither she will not earn with any Job nor he beloved parents will support us financially. My bad, after this incident Me and my mother have got infected with Covid, both have suffered very badly! Relatives friends came forward helped us a lot, which brought us back to normal life.. by God's grace. I tried to contact my wife over their this situation but call never connected. Seems she blocked all our phone numbers. I also tried emailing and messaging her. But no reply yet. My sister also tried contact her parents and sisters but no luck! Not sure what she is planning ahead. Kindly guide what should I do next?? What safety precautions (Legally) should I take to save my self?
