when words fall short

I'm sure you've heard it said hearts have windows
But mine has doors a painful past has closed
Unless someday they open wide
Revealing feelings locked inside
I'll love you more than you'll ever know

More than life
More than I've ever loved before
It's absurd and beyond words
I couldn't want you more
And when I try to pour my heart out to you
I'm not sure it shows
That I love you more than you'll ever know
(from "More Than You'll Ever Know" by Travis Tritt)
