I do not think you should break up with your boyfriend, although I am sure this situation must be very stressful and difficult for you. I think his parents will come around eventually if your relationship progresses into something more serious, because they will realize that in order to keep him in their lives they will have to at least tolerate you.
I was in a somewhat similar situation with my ex boyfriend. He was Latino, and so was his parents (obviously) while I am white. They always wanted him to end up with a girl from his home country, or at least one of the neighboring countries, and instead he brought home a born-and-raised Scandinavian. They absolutely hated me, and they were super aggressive about it. They would tell him to break up with me all the time, that it was a disgrace that he wasnt with someone from his home country like his siblings were, and would even physically intervene, such as taking the keys to his car so he couldnt come and visit me, and deleting my number from his phone. It was super stressful and I almost ended it with him. However, after a few months they realized that he wasnt gonna break up with me, and started to come around slowly. After a while me and my ex moved in together, and at this point they decided to at least try and build a relationship with me. It slowly, but surely got better, although they still absolutely hated the fact that i wasnt Latina. Me and my ex broke up after about 2 years though, for unrelated reasons, but by the end of it they would often invite me over for dinner and sent me sweet texts occasionally, and even invited me to come and visit their home country with them. I feel like this is the case for a lot of people who are in inter-racial/inter-religious relationships where racist/unsupportive parents are involved; they are super hostile and aggressive in the beginning, but they slowly come around because they realize that a relationship with their child is more important than their own ignorant beliefs. So I dont think you should end it if you truly love him, at least not yet. Things might get better.
I really do hope that things take a turn for the better for you, and that his parents manage to change their views. I wish you and your boyfriend all the best! x
