If I knew then what I know now

I filled all my nights

Thinking 'bout you

I spent all my days

Numbing the pain

Truth is I don't wanna face it

I was only for entertainment

I lived in my head

Running away

If I knew then what I know now (oh)

It would've been (I know now)

It would've been done

If I was a runner up (runner up)

You could've said that

And it would've been that (if I knew)

If I knew then what I know now

It would've been (oh)

It would've been done (done)

If I was a runner up (hm)

Could've just said that

And it would've been that babe

It's hard not to think about ya

I get stuck on how you got my hopes up

If your words were more than lies, I'd

Love 'em every time

If you were only genuine

Could've been more than friends

If I knew then what I know now (if I knew then)

It would've been

It would've been done (what I know now)

If I was a runner up (runner up)

You could've said that

And it would've been that (been that babe)

If I knew then what I know now (if I knew)

It would've been

It would've been done (it would've been done)

If I was a runner up (oh)

Could've just said that

And it would've been that babe

You were taking me for granted

It would've been done

Built this wall for you to damage

Save your lies for someone else

It would've been done

I know the game and I know it well

If I knew then what I know now (what I know now)

It would've been (it would've been)

It would've been done (done)

If I was a runner up (I was a runner up)

You could've said that (ohh)

And it would've been that

If I knew then what I know now (what I know now)

It would've been (it would have been)

It would've been done

If I was a runner up (up)

Could've just said that

And it would've been that babe (it would've been that babe)
