I am alone, but I still feel you on my bones
Baby, come home, to have your love would be a miracle
All these nights you are away
And all the nights we're both away
I'm sorry I'm not patient, dear
But I've waited through the years
And I never found the words to say
So you left me for another state
And I pray for you night and day
You will come and fill the hole you made
Now come and fill the hole you made
Maybe by May, but I still feel the shades of gray
All of the pain, but I feel it, too
Outline your misery on the outside of the sunrise
Down by the fireside, when you look in my eyes
Do you see a lifetime, and I never found the words
To say, so you left me for another state
And I pray for you night and day
You will come and fill the hole you made
You're my beautiful girl, my beautiful girl
In a broken world, you're my beautiful girl
My beautiful girl, we're getting closer
To where we wanted to be
The bruises on our chest, they go beneath
And when I failed you then, I failed me
We're getting closer to where we wanna be
And I never found the words to say
So you left me for another state
And I pray for you night and day
You will come and fill the hole you made
You're my beautiful girl, my beautiful girl
You're my beautiful girl, my beautiful girl
You're my beautiful girl, my beautiful girl
