Who do we marry?

You know that one girl (or guy)? The one you watch from a distance? The one and only whom if you could make her say yes, you'd marry in an instant?

But of course, she wouldn't say yes, which is why you didn't ask.

Are we supposed to ask her? Or are we supposed to be more practical in our choice of a spouse? Are we supposed to settle for the best of those who would say yes? The best fit?

I don't have any long thoughts tonight, I'm just stuck on this.
