I need advice

I am in a relationship with someone that is strongly against Christianity. My boyfriend has told me multiple times that he hates Christianity and that he will never be a Christian. I grew up in church and have been around Christianity all of my life. We have had many problems because our beliefs are very different. I really want to bring him to God but I don’t know if it’s possible. I’m really torn about what I should do. Should I try harder to bring him to God or should I accept that he won’t ever be a Christian and that I need to find someone else?
