I'm very stuck in my life. What should I do?

I met a guy last year. We are both doctors. He is pursuing his MD, and he belongs to the Gujjar community while I'm from the Gupta community. We dated for 2 months. I know it is not a long time, but I was very serious about him and got attached to him. He broke up with me due to caste issues. He asked his dad if he could marry outside their caste, and his dad said, "The family tradition will be ruined if there is an intercaste marriage, and wherever I say you will marry, you will do it." His dad neither asked about me and my family background nor took a stand for me. He said, "All decisions are taken by my dad, and we will not argue about this topic now." Now this guy is hooking up with different girls of other castes to satisfy his physical needs through dating apps. He asked me several times to meet and hook up. He wanted me to put in the effort to meet him and do everything like a girlfriend, but he ghosted me several times and then hooked up with other girls for his needs from Bumble. Then he pretended like nothing happened and asked to meet again. I have been stuck for a year and unable to move on. I have not even thought of any other guy except him. I want to ask, is it right to use a girl for physical needs but then do an arranged marriage according to his dad's legacy? In reality, he is OBC, and I belong to the general category. My family doesn't have an issue with intercaste marriage. I come from a financially stable family, and I have been honest and loyal to him. I didn't ask for a single gift or penny from him. He belongs to a BJP politician's family.
