I don't think it's weird at all. I've been with my girlfriend for 12.5 years, and still have no wedding plans. I'm sure we'll do it eventually, whether it's on a whim next week, or another 12.5 years from now. Regardless of whether there's a ring or a ceremony, we'll still be together tomorrow, and that's all that really matters to us. We've outlasted all of our friends' marriages, so we're doing something right, at least.
