Um, sorry to go against "team girl" (way to score points, Analog
), but I am female and I would tell you to run away from your girlfriend as well. This is definitely going to be a breaker, unless you have some hidden mystic in you or if she has atheist inclinations (are you an atheist?). I used to be one of those religious people, and I can tell you right now that if she makes you feel that way now, it most likely won't get any better over time (will probably get worse).
Unless, of course, she's Ustwo's wife...
Or like me, since I walked away from the religion thing eventually. But I wasn't a cradle Catholic, either. That's some deep shit you'd be trying to mess with. I wouldn't touch it.
