Didn't any of these issues cross your mind before you two became serious? I've thought about visiting church just to find a nice girl to be with. The reason I didn't bother was because I knew I'd need to continue visiting despite having achieved all I could from there. You two probably aren't compatible enough to stay together in the long term. Your girl is 'upset' you wont be together in the afterlife probably reflects her own understanding of this fact and she would most likely have her social network 'pissing' in her ear about the relationships failure, "because lets face it, you're not going to leave *your* faith, are you!?". I know it's a kick in the teeth losing out to a false belief but got to be practical. How would you raise (or want to raise) you kids?
