I'm Sorry lyrics

You said you wanted more than I could bring More than birds can sing You said you needed Time to find yourself But you found someone elseYou said I was your one and only You said with me that you'd never be alone And I drank in every lieI am sorry... I am sorry So here I'm apologising but one question keeps on rising Why... why?We've closed this chapter; leave the title till the end... "your lost and naive friend" We've built this tower. You built the steps of sand You don't care where I land You're holding someone elses handYou said I was you're one and only You said with me that you'd never be lonely And I drank in every lieI am sorry... I am sorry Here im apologising but one question keeps on rising.Why... tell me why
