Why'd i give it back?

You dropped my heart and it almost shattered
It hurt but to me it didn't matter
I fixed it up, and gave it back to you all bruised and battered

And again you let it fall
On my hands and knees i crawled
To collect all the pieces, only to have my heart look like an ugly ball

And yet i gave it back
It's now a nasty mess, beaten and blackened
It's left with an unfixable crack

And now there's nothing i can do
It's a lifeless mess after everything i let you put it through
And i still wonder... Why did i keep giving it back to you?
