Baby, I don't like how long this gone's been
I figured I'd hear from you by now
How am I supposed to tell you I was wrong when
Well, you won't pick up or turn around?

It ain't what you said, girl, it's what you didn't say
It's how slow you didn't go when you drove away

It ain't the goodbye, it ain't your taillights
That keep me up all night with a half-empty glass
Girl, it's the knowin' you won't stop goin'
It's startin' to sink in, it ain't the leavin'
It's the not comin' back

(It ain't the leavin')

Well, how we gonna pick up where we left off (Where we left off)
If you don't pull back in the drive? (Pull back in the drive)
Yeah, I was countin' on one more chance to give you all I got
And that's the thought that's drivin' me outta my mind

It ain't the goodbye, it ain't your taillights
That keep me up all night with a half-empty glass
Girl, it's the knowin' you won't stop goin'
It's startin' to sink in, it ain't the leavin'
It's the not comin' back

Girl, it killed me when you slammed that door
Knowin' you won't walk back through kills me more

It ain't the goodbye, it ain't your taillights
That keep me up all night with a half-empty glass (Half-empty glass)
Girl, it's the knowin' you won't stop goin'
It's startin' to sink in, it ain't the leavin'
It's the not comin' back

No, it ain't the leavin'
It's the not comin' back

(Startin' to sink in)
(It ain't the leavin')
