498a,325, 406 & 506 case by wife & Mutual onsent Divorce

I live in kolkata in a joint family married in Feb 2017, after marriage my wife had some issue with my mother then she always Pressurized me to separate or live with her parents then in Jan 2019 she left my home and started living with her parents. I try to make contact with her in between but she always asking me to give her Mutual Divorce. Then in Dec 19 i tried to contact with her parents & decided to stay separately. But few days later my wife file 498a,406,405 against me, my brother & mother & police 1st harass us in PS then after negotiating issue From 41 & said us to file Mutual Divorce immediately. Next we have taken bail along with Filed our Mutual Divorce petition(in petition no demand from my wife is mention) on 21 Jan 2020. Then the Investigating Officer regularly calling us & demanding big amount to close the case (FRT) & also harassing us. I also called my wife & her father They are not interest to run the case & saying after Final divorce in Aug 2020 they will make compromise petition & another thing is that at the time of leaving my house my wife took all the ornaments given by her father & me, also a Gold Ring & Gold Chain of mine. We also have writing proof of that. So my question is can we mutually close the case in court now or wait till Aug 20 for Final Divorce procedure and how can I demand my Jewellery back or any case i can file against them.
