My Husband Wants Divorce After Discovering My Real Age: Can I Save My Marriage?

My husband and I met through a matrimonial site in 2015. He send me request and called me over phone. At that time,I was doing as govt teacher job residing in an area which is 300 km away from my city. He met me at my rented house and proposed for marriage. He asked my age but I hesitated to tell my age as I was almost 40 years then. He told me that it would not matter if I would be older than him. He was also about to 4o then. I didnt tell my age age, as I wanted to get married, because I had my younger sister to marry. He was working in a different state that time. He sent his father to our home to fix marriage. His father asked my age but because of shame, I could not tell my real age. I told them Iwas 36. We were married in 2016 April. By that time my job was transferred to my ho.e city. So I was at my in laws home during 2016 and 2017. My inlaws i.e my father in law and my unmarried sister in law were never supportive to me. They always treated me as outsider. As my husband and me were livi g apart because of job we couldnot plan for baby. We both were pretty older to conceive naturally, so I contacted an ivf specialist. The doctor told that I have less chance to conceive naturally as my egg quality is not good. It was not impossible though. But since we were living apart, he suggested me to go for donor ivf. I was broken for a moment as I wont be able to give birth my own child. But I had to make my husband a father. So I went for do or egg ivf. In June 2018 a beautiful baby girl was born. I was very happy to get her. But pI noticed his father started to drink alot after her birth. He got tranfer of his job in 2019 and he took me from his ho.e to company quarter in home city in 2019 August. It was okay initially, but he drank a lot which I couldnot bear as l was from a totally non drinker family. He even said he could leave me but not drink. In 2020 hecame to know my real age from my matriculation certificate. He was seen upset, I apologise to him for not telling him my real age. I also told him about my and our family condition at that time. He cuddled me and said that he was not that kind of person. To be mentioned here, he is 6 month younger than me. But gradually his behaviour was changing, always treat badly at very very small things. In 2021 he again hot temporary transfer to a different place which is 500 km away from our homè. During this time he totally cut co tact with me. When I was having Corona and was hospitalized with my 3 years he didn't come to visit us. In 2022 January he was back home. He took my mother to stay with us. From March 2022 he started asking for mutual divorce. I was shocked. Since I didnot agree to that he filed a divorce case against me in 2023 August. Now It has been about one year, we are in concillation process. We are still living together. We are having physical also. Sometimes he becomes good but he always attend the concelling and says that he wants divorce for sure. I dont want divorce as my daughter loves him so much. I dont want to break the family, he is providing food, my daughter's school fees etc. I also do a job, so I dont need money from him. Only I wantvto stay as family.Is there any way to change his mind ? My job is contractual, so I dont have job security. He gets a handsome salary like 1.5 lacs per month with all medical and other facilities. Please suggest, how can I change his mindset or what may cause him to divorce me. I trust him. He also trusts me. He has mentioned only age criteria for divorce.
