Sophia, I've been around long enough to be well aware what Arwen was doing! [img]smilies/wink.gif[/img]
I meant that she (Arwen) saw herself as similar to Luthien - one of the immortal Firstborn, falling in love with a mortal.

Thank you Tar Elenion for your quotes.
Things now seem clearer to me. So it would seem that Arwen although half-elven,had elvish rights, and was happy to lay claim those rights until she met Aragorn.
The elves were certainly happy to claim her as their own - she was, after all, called the Evenstar of her People. (that is, the elves)
