I just thought that it was like that in the film because she had just 'made her choice', i.e. decided not to sail over the sea and to wait for Aragorn...and if the Ring survives, Aragorn will not become King (because Gondor will be destroyed) and she will not be able to marry him...and she'll probably die of grief. And if the Ring doesn't survive, Aragorn will become King, and she will die once she has lost all she has gained (i.e. Aragorn- apparently the children aren't enough to stop her from fading). Either way, her life is bound to the fate of the Ring- I suppose it simply meant that if she had decided to sail over the sea, she would not be affected by the fate of the Ring. But definitely over-dramatised.
