District Women protection officer is demanding 50 lakh rupees to be given to my wife to avoid cases.

My wife and I are married for 5 years and we are having a daughter 4 years old. Last year my wife deserted me without any reason and came back after 6 months. Everything was normal until 6 months and again deserted me after recording a diary in nearest police station stating that I am not allowing her to go to her maternal home. Then after 2 months of desertion a got a notice to appear before women protection officer near my wife's maternal home. I appeared there and she ( women protection officer) straightway said you give your wife 50 lakh and you can avoid any cases against you. Then I was allotted another date after 2 months. Due to prevailing lockdown I called women protection officer that it will be difficult for me to appear in front of her 4 days before the alloted date. She again and again harrased me and demanded 50 lakh to avoid any cases. I am totally devastated as my wife does not allow me to talk to my 4 yr old kid nor she is interested to live with me. We own a flat in joint name with my wife and I am the one paying EMI, My net income is 35k per month. Now she and her family demanding the flat and 50 lakh cash to avoid any false cases. From last one year I am bearing this harassment. I have also taken legal opinions and they said that nothing can be done until and unless there is case registered in your name. Please guide me.
