Lyrics:

Well, she said
She was not the one for me
And there was nothing
I could do to change her mind
And she said she was sorry
But some things aren't meant to be
She was unaware
She was robbing her heart blind
Oh, what she don't know
Is I'll always love her forever
Oh, what she don't know
Is I would have never done her wrong
Her under-estimation
Breaks her heart for sure
But she can't see what she don't know
Won't hurt her, but it's killing me

Deep in the shadows
Of a smokey neon light
I play myself
In a lonely game of pool
I chalk it up
As he sits down by her side
I take another shot
Swallow my pride
And I play a fool
Oh, what she don't know
Is I'll always love her forever
Oh, what she don't know
Is I would have never done her wrong
Her under-estimation
Breaks her heart for sure
But she can't see what she don't know
Won't hurt her, but it's killing me

Now watchin' her dance with him
Around that empty hardwood floor
Is like rubbin' saw dust in the wound
And I cry a little more
Oh, what she don't know
Is I'll always love her forever
Oh, what she don't know
Is I would have never done her wrong
Her under-estimation
Breaks her heart for sure
But she can't see what she don't know
Won't hurt her, but it's killing me
Oh, what she don't know
Won't hurt her, but it's killing me
