Talk about it with her if it somehow upsets you or something. If she insists, and you really love her you'll wait. I still think it's odd though, if you 2 réally love each other, as in real honest love, why wait? O well I can't think for her, so you'll have to talk with her.
But don't dump her because of that, maybe she just said it because she's scared or something, who knows. Talk about it, but don't force yourself upon her (and no I don't mean rape), asking for an explanation isn't weird, trying really hard to change her mind is a bad idea.
