Feeling butterflies for a non-Brahmin friend, my family disapproves: What should I do?

I have fallen in love with my male bestfriend and we love each other. But our castes are totally different and both of our families are against this. We are unable to leave each other and he is so obsessed with me that wants a casual relationship where we'll provide support to each others feelings until we find our serious partners in the future. What should i do? Should i part our ways or should i continue to be with him even though there's no future but we love each other more than anything. Is it good to have a relation that is more than friendship and less than relationship? I really want him but i'm afraid of what if i'll have flashbacks of him? Please help

hlo love gurus...i am here just to share my story and to know that have i done something wrong..... in 2018 .. it was my 10thclass final exams I met a guy on social media and he bacame my friend after that i came to know that his maternal grandparents are from my village and my family also have relation with them like families use to invite each other on occasions...but still we are living as friends.... In 2020 after my school is over i took admission in clg near to my home but after that i changes clg in one month and new clg was 150 km away.... but that was corona time so i was at home and after 1st semester i met with that friend and that day i felt something that i never felt before that feeling was amazing ..... after that we started to talk daily like i use to wake up with his call..... i use to sleep after talking to him.....in 1 month he told me that we can never marry because of family relation.. but i thought that when we both become independent our family will support us....and i told him to continue this till the time we can....and that became our daily routine..... i knew that that he is going to join a state government job that can be near to his home or in nearby district.... but after 1 month we get to know that he will have to join in shimla district so it could be easy for us to meet in 3 to 4 months...and i think it was easy to control my feelings for him him we dont meet regularly.. about when he came to join his posting was near to my clg.. just 12 km of distance.... after that we come closer i wasn't able to control my feelings .... now we both love each other and can't live without each other ... but now i am realising that he was right at that time that our family will not agree for our marriage,..... he thought that was destiny that we came closer ... his posting could be anywhere in the state but why near to my clg...... now sometimes i feel that God cheated me ????now i don't know whether we have done something wrong by loving each other.....his family is forcing him for marriage... and we can't do anything now.... i am not able to accept that... and after knowing this that his family is looking a girls for him to marry I am getting more attached to him.... i think i totally messed my life ????
