Regarding marital issues and notice received from my husband

I got married in May 2019 and it's an arranged marriage. both of us are software engineer. Before marriage, my husband and his family hid about their debts. After marriage, they started forcing me for loan to repay the debts. I refused for the loan,But I helped them by giving some money for their problems. But their greed increased. Problems started when I conceived and I was asked to abort but I declined. Later, my mother in law started troubling me with no proper food and giving some food items which was not good for my health. My health condition deteriorated, even after saying to my husband, he was not ready to leave me in my parents care. And my mother in law always used to abuse me for getting pregnant. She used to tell me that I could have got pregnant without getting married. And due to constant abuse from my mother in law, unable to bear the torture , I asked my husband to drop me in my parents home when I was 5 months carrying. And my husband used to speak to me on phone, but he never came to see me or never took me to a doctor. My parents took care of me and I was also admitted twice before delivery due to health issues and no proper care till the time I was in my in laws house. A week before delivery my husband came to see me and I gave birth to a baby girl in Feb 2020. My in laws came and saw the baby in hospital. Later in the hospital, my husband asked me for money for his sister and started crying, due to which I called my mother in law and asked her to stop making debts. And my mother in law hurled bad words at me, saying that it's her son, she can do anything. Then I came to my parents home after discharge and before my baby completed 11 days, my mother in law came with her relatives to insult me. They even asked divorce, which I declined. When I said for the sake of my daughter, I don't want to go with divorce now. Then my husband's uncle said, that since I am earning , I can take care of my daughter alone and she doesn't need a father. And they even accused me for not aborting my baby. My parents kept quiet and they for the sake of me and my daughter, they dint say anything. But after 2 months, my husband came back to see baby. He was good with us. But later , he started to ask money citing reasons of debt or selling home or starting a business. I clearly declined for everything. Then he started forcing me for loan. Then my parents asked me to start building a house in the site that my dad owned. I started building it with my parents help. Due to this decision, my husband stopped coming to see my baby after she was 6 months. Now she is an year old. My parents invited them for birthday, but none of them turned up. Now they sent a notice asking me to return back in 15 days and said nonsense stuffs. I have replied back to them saying that whatever they said is false and also they asked me to leave my job and return, else I need to apply for divorce. What can I do after sending the notice reply?
