What happened to Galadriel?

[Tar Elenion]

According to the Judgement of Manwe anyone with any mortal blood is mortal unless granted other doom. By the Judgement the amount of blood is unimportant. What is important is if Manwe sees fit to grant other doom.
Elladan, Elrohir and Arwen were all granted other doom, and this doom was different than that of Elrond and Elros (who had to choose their fates immediately). They were allowed to live with the 'youth of the Eldar' until the time came for them to make their respective choices. The essential difference between Elves and Men is not how long one or the other may live, but rather what happens after death. Although not specifically stated in LotR, it is implied by the Appendices that Elladan and Elrohir chose mortality. However in Letter 153 JRRT writes: "Elrond passes Over Sea. The end of his sons, Elladan and Elrohir, is not told: they delay their choice, and remain for a while", which has some accord with the Prologue: "There, though Elrond had departed, his sons long remained, together with some of the High-elven folk."
"Remained for a while" and "long remained" implies that they eventually departed.
JRRT seems to have left it up to the reader to decide whether 'departed' means 'died' or 'sailed West'.
