It's never too late, but woo is something people have to think their own way out of. Humans have a tendency to push back when pushed, persisting in trying to deconvert her could damage your relationship with her. We often complain about people shoving their religion down our throats, we should be self-aware enough not to turn around and try to shove atheism down theirs.
Echoing some other posters, encourage her to read the Bible, on her own, without your commentary. If she wants to discuss something, discuss it, but don't waste the precious time you have together taking potshots at her faith. I'm in a relationship with a believer, we respect our differences, and we get along fine. YMMV, but I think you should try it.
