Received notice from advocate on behalf of my husband

I am a housewife wife with 2 children, we live in city, my husband is saying he can't afford expenses here and he left the house and went to his village. He didn't pay the school fee of my son. My mother paid the school fees. In the call recording he states that he will not pay anything. My mother paid house rent. I went to police station and filed a case against him. Police called him to discuss, he said he will come in 2 days. We were waiting for the call from police for update. Suddenly i received a notice from advocate on behalf of my husband stating all false statements that I have been torturing him, asking money for my parents help, I am expecting a lavaish life..etc. all false statements. He is asking me to come to Village in 7 days. I have filed case on 16th October 2024, and i received notice dated with 22nd Oct 2024. My son school is in progress, my parents are daily workers. I don't understand what to do, i will become burden to my old parents, if I go to Village my childrens life will be spoiled.
