I can see what you're saying (and I completely agree), but some parts of the movie made me think there was also some attraction to her.
Their first encounter, after V saves her, with the expanded diologue, it made V sound a little flirty to me.
Also, when V's cooking the day after, and Evey sees his hands, it sounded like V was saddened that she was potentially repulsed by his scarred hands.
Him asking her to dance also gave that idea. He almost reminded me of the guy asking the hot girl to dance at the dance, but in the slightly nervous/excited way, and not in the immature bastard high school way.
Finally, his death scene. He says blantently that he loved her and that she was the one who opened his heart again.
I agree there was love, but I think there was a hint of V yearning for her, to make his love become his lover.
