A common joke I've seen online is that Bruce Wayne can't seem to date a woman without her either A) dying or B) eventually finding out he's Batman. I know of several cases where he entered a semi-serious relationship with a woman, but oddly enough both criteria apply to those (usually the latter one). So this leads me to believe that the joke is based in reality after all.
Has Bruce Wayne/Batman ever been in a serious relationship with a woman who did NOT die or learn of his dual identity?
All media acceptable - comics, movies, cartoons, whatever. I assume there won't be too many answers, since I'm looking for actual dating relationships and not just the "arm candy" he occasionally employs for appearances.
