You say I'm heartless

And you say I don't care
I used to be there for you
And you've said I seem so dead, that I have changed
But so have you

refrain:
Guilty, guilty I feel so
Empty, empty you know how to make me feel

You've been so thoughtless
I can see right through you
You used to be there for me
So don't you leave say goodbye
'Cause you have changed but so have I
