Wife Threatening of 498A after Filing MCD but not appearing.

My marriage was under section13 of Act XLIII of 1954. Marriage was in December 2017 She left my house on February 2019 We had arguments but no physical violence ever. No police complaints either side. We filed for Mutual Consent divorce on April 2019. Her friend whos a lawyer arranged everything. After a month she stopped contacting me and didnot attend any hearing. I attended all and dates were taken. I changed my lawyer after taking NOC. The lawyer is now threatening me that they will file 498A and Dowry case and Streedhan case against me unless I give my wife my mother's jewelry or 5 lakhs cash. When she left, I was in office and she took all her jewels (both sides) and clothes. Some clothes are still here which I am ready to give back. I cannot give my mother's jewels and I don't have 5 lakhs to give to her. They are threatening to arrest my family and me. My father is 80. Severe heart patient and highly diabetic. Nearly blind. My mother has had two heart surgeries and is under regular medication. What should I do?
