How do i proceed?

I am married to a US citizen for 2 years and we have a son of 1 yr old. Because me and my husband are not able to come to an agreement/terms of our marriage conflict, i have decided end the marriage. During the period of my decision, i was visiting my parents with my child back in my home country.
My husband had filed a petition for dissolution of marriage under the IL divorce law, alleging that i have caused extreme mental cruelty to him and his parents. He had claimed that i have taken all my personal belongings. His lawyer had set the court hearing date which i am not able to attend because i am not residing in US anymore.
The allegations made on me are completely untrue.
I didn't take anything back with me because i only had the intention to visit my parents.
