Falling for an atheist. Any spiritual advice?

His name is Jasper, and we've been friends for about two years now. He's really awesome, sweet, funny, and we share a lot of the same art and music interests. At the same time, though, we're very different people. I'm taking acting courses; he's working towards a degree in engineering. I'm a very emotiona/spiritual person; he's very analytical. I know that according to the Meyers-Briggs personality test, I'm an ENFP, and just from knowing him for as long as I have, I'm pretty sure he's an ISTJ - the exact opposite. In spite of all our differences, though, we get along incredibly well - opposites attract, I guess? Anyways, recently I've been developing strong feelings for him, and he admitted that he likes me as well. I really feel like we could have a chance at something, but I'm heasitant because of our different beliefs. I'm a devout Christian, whereas he's decidedly atheist. He's very logical, and is reluctant to accept anything that can't be physically, scientifically proven. Is there a way to overcome these differences and still have a happy relationship, or should I just stay friends with him and not let my heart lead for once?
