Narcissist wife

Hello Team, I married a narcissist wife. December 2022. Her family force fully married her. She was having an affair with multiple people. She use to introduce as a friend later on got to know they are boyfriend and having affairs with then. I got her being an affair with one guy. She said don't justify my character we will get mutual divorce and get separated in month of November 2023. Previously also she never use to stay with me 3 days at my and 5 days at her home. I took her to psychiatrists she I suffering from some disorder. Which could have healed her but because of her mom everything messed up. Now It has been more 6 months we got separated she I ask for ornaments which was given by her family to me. I said I will submit ornaments at the time of divorce or I will handover to your family. She is denying for everything and saying give me ornaments in personally or otherwise I will harm my self. Really stucked in life don't know what to do. Should I submit ornaments or file a case. Even their family members are not responding the calls or text messages.
