So you say that I can trust you, baby
But I'm scared of being hurt by you
Could you promise me a thousand times
Your every word is true

I'm feeling weak, I'm feeling so unsure (I'm so unsure)
I'm so afraid, I'm feeling insecure (so insecure)
I see danger lurking everywhere
And that's the cross I bear

I got a heart of glass, a heart of glass
And you know it's only beating for you
A heart of glass, a heart of glass
So you better be careful what you do
With this heart of glass
(With this heart of glass)
With this heart of glass
(With this heart of glass)
This brittle heart
(Ahh)
Don't make it fall apart

Now you swear we'd never fall to pieces
Trying to soothe me with your sweetest words
But I'm holding back to open arm
Because I know love hurts

I'm feeling weak
I'm feeling so unsure (I'm so unsure)
I'm so afraid, I'm feeling insecure (so insecure)
I see danger lurking everywhere
And that's the cross I bear

I got a heart of glass, a heart of glass
And you know it's only beating for you
A heart of glass, a heart of glass
So you better be careful what you do
With this heart of glass
(With this heart of glass)
With this heart of glass
(With this heart of glass)
This brittle heart
(Aah)
Don't make it fall apart

Would you promise me, promise me?
Would you promise me?
Would you promise me, promise me?
That you'll never leave
I need honesty, honesty
So tell me honestly
Are you here to stay?

I got a heart of glass, a heart of glass
And you know it's only beating for you
Got a heart of glass, a heart of glass
So you better be careful what you do
With this heart of glass
(With this heart of glass)
With this heart of glass
(With this heart of glass)
This brittle heart
(Aah)
Don't make it fall apart
