If Only You Knew

It's just a phrase, it's just three words
But it's what I want you to say
When you go by, my heart is tellin'
Me that this won't go away
But right now, I'm just lost
I know this love don't come without a cost
Your laugh, your smile, your eyes, your voice
This is why I fell in love with you
But if I tell you how I feel
I'm just scared of what you'd do
I've really got to think this through...
If only you knew
