My boyfriend cheating me

Hello sir I met a friend of my graduation in march 2021 through Facebook. He's working in government sector Mumbai and I am from visakhapatnam. We both loved each other, had physical relationship also, we planned our future in Mumbai. Few months later, in end of June, he said that his parents will not agree for our marriage and he asked for breakup. But I couldn't as I loved him so much. Later we again continued our relationship even physically, but later he didn't promise me anything about our marriage. His parents found a match for him and he got ready for marriage with that girl. Somehow they got to know about our relationship and that match got cancelled. This happened in March 2022, from that day he was not talking to me properly, his parents were saying that we can't agree for your marriage, he was simply saying that I didn't love you anytime, I just cheated on you, I don't want to marry you, I didn't promise you that I will marry you. Now what can I do? I don't want to file a case as he will get more angry on me, also it troubles his job. He's the only source of income for his family. Also I want to marry him with acceptance from him and his parents. Also I don't have much proofs, we used to save all our photos in his phone and he deleted everything. I have only 2 3 General photos and some chatting proof like he said I love you to me and also chatting when he asked for breakup. I don't have any conversation proof like promise of marriage. I even said him I can't live without him, and I will die if he leaves me. He is not responding to my messages and sometimes simply saying not to harass him. He's getting suggestions from his uncle who's practicing law. But I don't have anyone to contact Please suggest.
