Non compliance in paying Ad Interim Maintenance in a DV and Child Custody Case

Hello I had a love marriage in 2012. He began engaging in mild DV in 2012. He has major temper issues which I was completely unaware of before marriage. I was contemplating a divorce, but he assured me he would take the efforts to change for better. Since family reputations were are stake I decided to give him another chance. We went to the US in 2013 when I was expecting my first child. Our daughter was born in Oct 2013. DV incidents grew from bad to worse. He kept imagining that I had an affair with "someone". I was not allowed to go out in the US on my own. Talking to neighbours was curtailed because he thought I was complaining about him. Since my daughter did not socially interact with a lot of kids she showed delay in speech and she was diagnosed for Autism.This went on for 5 yrs. In 2017 he abused me verbally in front of my baby daughter and asked me to leave US with her. He refused to pay for the flight. My retired parents arranged for the same somehow. Once in India he began to pretend that he was really concerned about the welfare of his daughter. I filed a DV Petition in the Family Court in Bandra BOC in 2017. Instead of replying to the DV Petition he changed the focus of the case to the child custody stating that my daughter was Autistic and had to immediately move to the US to recieve appropriate treatment. Since my daughter was socially exposed to kids of all ages and different people while in India she improved drastically. So much so that I have an email from the University of Washington this year saying that my daughter no longer needed any therapy. Family court granted him 4 overnight acceses prior to the lockdown this year. The 4th overnight access had to be postponed due to the Pandemic. Last month he threw a tantrum that he wanted to immediately avail of the pending overnight access of my daughter. He planned to rent an apartment in our current City during the Pandemic. We tried to reason with him about the same. I did not deny or refuse the overnight access, I just asked him to wait till the Pandemic was over. He has been availing of my daughter's videocall access 5 days a week since Jan 2020 because he was in India (so it wasn't that he wasn't speaking to her at all). Court granted an Ad Interim Maintenance for my daughter in 2018 of RS 25k per month. Since I did not conform to his demands of overnight access he has started paying me reduced maintenance for my daughter. I work in the travel industry which is now shut during the Pandemic. It is expected to resume in 2021. He suddenly left for the US last week. The 5-days-a-week videocall access is no longer valid since no such details were agreed in the court. He is now threatening to stop the maintenance completely. He had threatened me in 2017 verbally in India that he would make sure no school admitted my daughter. I need to know if I can file an FIR against him for threatening to reduce or stop my daughter's maintenance. She cannot suffer for our differences.
