Reassurance

This is a poem to make a certain someone happy.

I'm not sure how to prove
         What you should already know.
In what way do I show you
         How much I love you so?

At one time you believed,
         That I did hold you dear.
How should I now convince you
         That I still need you near?

Do I tell you, over and over,
         Those three words, worn so thin;
Tell you, time and time again,
         Until you finally grin?

Or do I speak of something else,
         Perchance, the times we share?
All the good and joyous days;
         All the moments of despair.

Shall I remind you, instead,
         Of times more intimate?
Surely so many nights of passion
         Can't be illegitimate!

I can write all day about it;
         I could put it in a song;
Maybe, I'll get it published
         So it could last centuries long!

It's in all my letters;
         In everything I do;
Every time we touch and speak,
         I'm saying "I love you!"
