I know the look that you get when something's on your mind
How you overthink every little thing trying to get it just right
You wear a smile when you sleep at night
Call your mom when you need to cry
I never thought that I would be the reason why
I thought you knew how much I loved you
Thought our love was a long and winded road
It's more like a highway heartbreak song
Playin' on the radio
Thought I saw forever in your eyes
Never thought I'd hear you say goodbye
But you were already letting go
Oh so what do I know...
Flippin' through pictures of you on my phone
You know I try, but I can't find where it went wrong
Without a trace, what happened to
The life we had, the girl I knew
The one I swore that I would never lose
I thought you knew how much I loved you
Thought our love was a long and winded road
It's more like a highway heartbreak song
Playin' on the radio
Thought I saw forever in your eyes
Never thought I'd hear you say goodbye
But you were already letting go
Oh so what do I know...
I know nothing but a heartache baby
I know you're leavin's gonna drive me crazy
Yeah drive me crazy
I thought you knew how much I loved you
Thought our love was a long and winded road
It's more like a highway heartbreak song
Playin' on the radio
Thought I saw forever in your eyes
Never thought I'd hear you say goodbye
But you were already letting go
You were already letting go
Oh so what do I know...
Yeah what do I know...
So what do I know...
