Why Can't I Forget Us

I burned the pictures but the flames won't rise
Your voice still echoes in the back of my mind
The clock keeps ticking but it's stuck on rewind
I'm free but I'm chained to the time we aligned

I built these walls but they crumble at night
Your shadow dances in the absence of light
I'm running forward but I glance behind
The love was poison but it felt so divine

Why can't I forget us
Erase the scars and the dust
You're the ghost I can't adjust
But why can't I forget us

I tried to drown it in a sea of new skies
But your name still lingers when I close my eyes
I told myself I'd never look back twice
But here I am lost in your lies

Do I block it out or let it fade
Every memory's a hand grenade
I want to hate but I'm just afraid
Of losing the mess that we made

Why can't I forget us
Erase the scars and the dust
You're the ghost I can't adjust
But why can't I forget us
