It's a bit of a straw-man to say that adding a single element of magic makes a romance story fantasy. But, writing by its nature is not able to be delineated by fences. It shifts and changes. It is a thing that constantly evolve. Before modern fantasy the only supernatural stories you had were fairy tales, horror, and myths. But after Tolkien, Lewis, and others we have fantasy. This too broke down into more sub-genres like urban fantasy, regency-romance fantasy, and some are even combining sci-fi and fantasy to create sci-fa. It's not a problem, that's just the nature of the beast.
I also think fantasy is like porn: you'll know it when you see it.
