"Dark Side" lyrics

I've never been here before
I gave you all my heart and more
So why couldn't you give me yours?
What was I missing?
Don't act so indifferent

Now why are you acting
Like all that we did never happened?
What did I do?

Is this the dark side of love?
Is this the dark side of loving you?
Is this the dark side of love?
Is this the dark side of loving you?

Was it for another man?
'Cause maybe then I'd understand
You had my heart right in your hand
I said it was fragile
But you weren't even careful

Now why are you acting
Like all that we did never happened?
What did I do?

This is the dark side of love
This is the dark side of loving you
This is the dark side of love
This is the dark side of loving you

'Cause I fell in love with what I thought we'd be
Now it's all falling apart at the seams

This is the dark side of love
This is the dark side of loving you
