My 11 years boyfriend broke his promise of marriage saying his parents are not agreeing

My Christian boyfriend and I were in 11 years relationship. He promised me to marry and I trusted him mentally and physically. When I said about my relationship in my family he said he will also discuss with his parents but he never did. For 2 years I waited hoping he will discuss with his parents but no. He started forcing me to convert and all we had argument and I said breakup. I didn’t even contact him but he for 1.5 year he kept contacting me asking his parents are forcing him to marry so he asked me to accept for the marriage. I didn’t have any trust left on him so I rejected that. But after few months he was in accident and contacted me. After 2 days of checking in his health he started again asking for marriage and saying this time he is serious. I asked him to discuss with his parents first he said he is going to discuss with them so I trusted him and patched up. His father was ill and suddenly he met with another accident this all took 6 more months without him speaking to his parents. In 2024 March my parents agreed to the marriage and asked me to connect with his parents but still he kept on giving excuses and my parents were very angry seeing him so reckless. With my parents call he discussed with his mother and asked me to speak with her. He was in conference and infront him she started insulted me he kept messaging me to stay silent until the marriage so I didn’t speak anything in return. After a week we arranged a call with both our parents. Again his mother spoke in very rude manner but this time with my mother. She even spoke ill of my caste when they belongs to the lower caste. My parents are not ok with that family so they rejected him. I called his mother to settle this calmly but this time she crossed her limits completely and spoke very badly about my character and my upbringing. I said everything to him but he said to be calm again. I couldn’t be patient anymore with his attitude when he continously contacted for 1.5 year asking to marry. Now still he says let’s wait until his parents agree even if it takes 1 year or 10 years. Moreover he says his parents will live with us after marriage. Now he is forcing me to leave my job and move to his location. And forcing the religion on me. This time I don’t want to stay silent I want to file a case n him for constantly contacting me for marriage and after I accepted he started forcing conditions and take his mother insults. I have all the message proofs where he contacted me and asked me for marriage.
