In Feanor incident, there was not Celeborn about yet, was there?
Funny how Galadriel rejected Feanor to grant some Gimli's wish

. But she changed over time, haven't she? I mean, she was arrogant at first, and 'wished to have realm of her own' (of course, I messed up the quote, excuse me), and in the end 'I will remain Galadriel and diminish' (another mess up, I reckon, please someone with teh book handy correct me, please).
And Celeborn was referred to as 'Celeborn the Wise' Wise men do not make the fuss about 'admiration'. Besides, I reckon Gimli's was kind of Quixotic one (I mean, remember how that funny Don loved his Dulcinea? He was contended that she was there, not asking any more, and ready to do deeds (I mean, heroic, sort of) for the glory of her name) Gimli almost made a duel with Eomer for the glory of Galadriel's name. Chivalry. Chivalry allows for admirers to exist without making husbands angry. I mean the code allows it.
