Marriage!

[Encaitare]

One thing that does not seem to have been mentioned is that Sam was a ringbearer, if only for a short time. He probably felt some form of loss when the Ring was destroyed, and for his part he was due some reward in the undying lands when the thing that bound him to middle earth most (Rosie) passed away.

Well said, shia'tan! He probably did feel a small loss, since the thought of taking the Ring for his own and using it to become powerful (albeit with good intentions) did cross his mind.

it is possible that Frodo had passed through his dream of music and his life had passed when Sam arrived. Does not really fit with the conceit of the relationship between them, but is still a possibility.

Aw, but that's so sad! Well, I looked up the dates and did the math, and determined that Frodo would have been 114 by the time Sam joined him. Since hobbits can live to be well over 100, and living in the Undying Lands would probably bring longer life even to mortals, I think it's safe to say that Frodo was still alive, although very old.
