Christian vs Buddhist dating?

I am Christian. I’ve been seeing this guy and recently found out he is Buddhist.

What are similarities and differences between our beliefs? I never thought I would be with someone with a different religion as me.

But he’s everything I’ve ever wanted. He’s sweet, he’s just amazing. He treats his mom wonderful and takes care of her (she has cancer) and he treats me better than any man ever has, including my own father.

I don’t wanna let him go though. But how can I make us work? Would it be greedy of me to try and convert him to Christianity? Help.
