I think you mean luthien. Arwen went on living for years after aragorn died and she was a half elf who had chosen to become human. And actually a lot did happen in those thousands of years, the only thing that stopped them from weakening more quickly was the elven rings of power and they only slowed the weakening of the elves. Also it specifically said in the silmarillion that elves aged NOT through grief but over time from their spirits burning them out, it took a long time but it happened.
