Appreciation From A Distance

I am, to her, today,
The present.
And I wish to be her lifetime.
But I have no chance of being
   her future
If I cannot out-do her past.
But she, being human,
Only has one heart,
One she has already given
   to someone else.

But I have said my prayers,
And I pray not that I be
      the one
   she spends a lifetime with,
But just her to be the happiest
   whoever she ends with.
