What Do I Know?

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
