Whatever made you change your mind

I can't believe that you would walk out on me
Why did you tell me that you loved me?
What did I do to make you treat me so unkind?

Whatever made you change your mind?
na-na-na-na na-na-na-na

Your love for me has changed, without a reason why
You said you needed me, I guess that was a lie
'Cause now today I find, you're leaving me behind

Whatever made you change your mind?
na-na-na-na na-na-na-na

You're not the same as the day you took my name
And now you're slipping through my fingers
It seems like yesterday that all your love was mine

Whatever made you change your mind?
na-na-na-na na-na-na-na

You said we'd work it out, I think that's only fair
I gave my life to you, now you don't even care
And now today I find, you're leaving me behind
Whatever made you change your mind?
Whatever made you change your mind?
