Tell me you're as light as a feather and i'll believe it

I can't shake the feeling that all of this is futile and that if I melted my heart to gold it just still wouldn't be enough.
You looked into my eyes and reached into my soul, never knowing what you could find. You stayed up feeding me stories of history and all the parties of times gone by. Now realisation hits you in the morning and you look at me and laugh, you tell me the stories weren't meant for me and I was just something to pass the time. Do you still feel sick when you look at me because, my senses seem to desert whenever you're around and I can't help but feel I'm missing out on all the fun.
Someone told me that they saw you the other day, walking down the street with a pretty girl on your arm. Well I might not be as beautiful and I might not be as free. But I was safer than anyone will ever show you again. And no one will ever want you quite as much as me.
Don't be that guy that I could never reach even when I knew I was supposed to. Don't be that little too far away. Don't stop me counting the odds and placing all my coins on you.
Well if you care and if you're asking, I bought this locket once and I put a photo of your face in the little gold heart and I wore it round my neck until it was so heavy that it hurt. But I never told you because I didn't want to give you another chance to leave, I couldn't have you thinking that you weighed me down. Because all the weight in the world couldn't stop me from lifting you if you asked.
