What hurts the most by Rascal Flatts

What hurts the most
Was being so close
And havin' so much to say
And watchin' you walk away

And never knowin'
What could've been
And not seein' that lovin' you
Is what I was tryin' to do

It's hard to deal with the pain of losin' you everywhere I go
But I'm doin' it
It's hard to force that smile when I see our old friends and I'm alone
Still harder gettin' up, gettin' dressed, livin' with this regret
But I know if I could do it over
I would trade, give away all the words that I saved in my heart
That I left unspoken.
