Very fair was her face, and her long hair was like a river of gold. Slender and tall she was in her white robe girt with silver; but strong she seemed and stern as steel, a daughter of kings. Thus Aragorn for the first time in the full light of day beheld Éowyn, Lady of Rohan, and thought her fair, fair and cold, like a morning of pale spring that is not yet come to womanhood. And she now was suddenly aware of him: tall heir of kings, wise with many winters, greycloaked, hiding a power that yet she felt. For a moment still as stone she stood, then turning swiftly she was gone.

See, Tolkien? It doesn't take much to give us some romance. One beautiful paragraph sings it clear. And you even follow it up with two more moments in the same chapter: Éowyn's hand trembling as she brings Aragorn the wine cup, and her gaze moving to him while saying goodbye to Théoden before the men set off to Helm's Deep.
And this isn't even a couple that ends up together.
So if you wanted us to feel the Aragorn/Arwen bond, all you had to do was give us *one* such paragraph describing something similar between them, somewhere in all the pages of The Fellowship of the Ring. On basically every page you give one beautiful paragraph to the scenery or weaponry, or you recite several stanzas of a poem. So why merely a few murky enigmatic hints about Aragorn and Arwen's love, when it's got such emotional potential (a long-lived Elf giving up her immortality for the future King of Men!), and would only have taken a moment like the lovely one you just gave Éowyn? If you'd done so, maybe a lot more people would love Arwen, or at least like her half as much as they adore Éowyn. I, for one, would have appreciated it.
I know. I can't stop editing when I read nowadays. It's an affliction.
