Grace Potter - Empty Heart lyrics

You know how to make me weak in the knees When you pour yourself all over me But somebody broke you back in the day Now you never ever love Now you only wanna play I cry when you do, I cry when you don't Why won't you tell me what, what you want with me One day we're together then we're apart Why won't you let me fill up your empty heart There's a big old hole in the middle of you 'Cause somebody left you black and blue Yeah we all make promises we can't keep And they're paper thin but cut so deep I cry when you do, I cry when you don't Why won't you tell me what, what you want with me One day we're together then we're apart Why won't you let me fill up your empty heart Why won't you let me fill up your empty heart Fill up your empty heart Fill up your empty heart Fill up your empty heart Fill up your empty heart (I just wanna fill it up baby) Fill up your empty heart (Why won't you let me) Fill up your empty heart (I want you to let me) Fill up your empty heart (I just wanna) Fill up your empty heart (Fill it up, fill it up, yeah) I cry when you do, I cry when you don't Why won't you tell me what, what you want with me Fill up your empty heart Fill up your empty heart One day we're together then we're apart Why won't you let me fill up your empty heart Fill up your empty heart Fill up your empty heart I cry when you do, I cry when you don't Why won't you tell me what, what you want with me Fill up your empty heart Fill up your empty heart (I just wanna) Why won't you let me fill up your empty heart
