Owner of flat

I got married in 2002 and did all for my wife. I supported her in higher studies and all life needs. That time her parents is against us. I purchased a flat in joint name of me and wife in 2009 which was registered in 2013. All the payment was done in cash or joint account but she was not earning before 2011 and not a single penny paid to the builder. All the money receipt given by builder is by my name as I had paid all the amount . In 2011 she got job in bank as PO and have had an illicit relationship with her co-worker in bank. I paid full payment for two flats under her bank projects which was booked on her name. Also she started cheating bank by taking bribes for issuing loans and using fake stamp paper supplying I stopped her for all this ill practices. My only son who is now 14 years old had caught her in intimate position with the co-worker in my flats many times and informed me with audio and call records proofs. When I stopped her and informed her parents and shown all the proofs they all started torturing me mentally physically economically and threatened me to shut my mouth or they will kill us or false case may be filed. At last they all thrown me and son out of flat and since 1.5 years she was living in flat alone . I have a private job where she complained and now I am jobless. She filed 498A in Patna and my whole family's names is given and after a long struggle we were on bail. She has political, bahubali approach and her parents is supporting her due to her job and she is earning . Now I want divorce and my earned flats back although I have threat of my life but what should a jobless father leave for his son? Is there any solution.
