That's fair. But, I don't see your interpretation of the dancing. Maybe it's because Radcliffe and Watson had the chemistry and talent that Gint doesn't have, but I never saw that level of closeness or love between Hermoine and Ron and it seem to me to be more than friendship. Frankly, Hermoine is much like Harry's mother . . . and Harry is "just like his father" to some extent. So that's part of why I think that relationship makes more sense.
In addition, maybe it's just because I'm not a romantic, but what is love other than a close friendship with a shared physical attraction?
But, all these things are open to interpretation, and maybe my interpretation isn't shared by everyone or even the majority.
