Not Enough?

If you felt my heart beat
would you know I was sincere
truthful
honest
free?
If you laid your hand
flat on my chest
and watched my eyes flutter
heard my breath quicken
lips part
whispered words
would you believe me
then?

What do you need to hear
to know that I am
only with you
only for you
only wanting you
only needing you,
What exactly should I say?

There is no proof that I can think of
no promise that would not seem
meaningless
no words that carry real weight
no tears that wash away past guilt

I promise you that I am here
with you
right now
why isn't that enough?
