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
