The Fellowship remained in Lorien for a month, though they were not aware of the passing of time. Unsurprisingly, the decision to leave had to be taken for them, although the Lord & Lady did present the opportunity to remain, if any so desired.
Whether they stay or go, none can be sure of peace.
Maybe the paths that you each shall tread
are already laid before your feet,
though you do not see them.
The final gift-giving and farewell scene is heavy with poignancy as the Fellowship collectively realise that they are now fated to head away from stainless beauty and restful peace, and towards the dark, the dangerous, and the unknown.
Memory is not what the heart desires.
Alas for us all! And for all that walk the world these after-days.
For such is the way of it: to find and lose,
as it seems to those whose boat is on the running stream.
