But also because she knows that she and the photographer have already taken each other to the perfect and beautiful world. And that now it’s time to descend to the actual one. If they try to live in that other world for good, it will recede into the distance; it will be as if they’d never been there at all. She says goodbye, and they long for each other for the rest of their lives.
…
And this is why Francesca’s story couldn’t have ended any other way. She couldn’t live happily ever after with the photographer, because he represented not an actual man, not even the “perfect” man; he represented longing itself.
…
If you’re this obsessed, it’s because he represents something you long for.
