Closure - Oxygen lyrics

I can't sit back and watch
You jump in the deep end
With him as your oxygen
'Cause it's a long way to fall
When you sink to the bottom
Hoping he'll change again

You're drowning in tears
And how can you breathe

Underwater
Believe those lies much longer
He cheats you, deceives you
With heavy hands he holds you
So cold, with a heart of fool's gold
Caught in the undertow

You'll always be the one
To say there's no black and white
Well I must be colour blind
'Cause it's a long way to fall
When you sink to the bottom
Leaving it all behind

And I know it's hard
To see through it now
'Cause he says he'll change
As he's pulling you down

I can't sit back and watch
You jump in the deep end
With him as your oxygen
