Your pretext of writing "I love you" in the book was a great idea. It's unlucky that there was confusion with the names of the neighbour.
Love happens in mysterious ways. Maybe if you had not relocated, a twist of fate would have brought you two together, heh?

Just a note; there were some errors with the pronouns (he and she) throughout your story. Maybe naming the protagonist, perhaps with a common female name could help to lessen such errors.
Great story that sparked the imagination of love and what might have been:)

Thanks for sharing your story with us.
