I used to be all alone
Empty house, empty home
And then you came along
Now my heart is gone
I never knew what pain was
Now the world's dangerous
So many edges
All coming to get us

That's why it hurts when I love you
That's why I have to have you by my side
That's why it hurts, it's supposed to
That's how it feels when you do it right
That's why it hurts

I used to laugh, now I cry
And the truth is I lie
Next to you every night
Totally terrified
The more in love that we fall
The more I'm out of control
And baby if I lost you
I don't know what I'd do

That's why it hurts when I love you
That's why I have to have you by my side
That's why it hurts, it's supposed to
That's how it feels when you do it right
Feels when you do it right

So don't ever leave me
Don't ever leave me
No, don't ever leave me alone
Pain is a feeling
You feel when the real thing
Stops your breathing cold

And that's why it hurts when I love you
That's why I have to have you by my side
That's why it hurts, it's supposed to
That's how it feels when you do it, feels when you do it right
That's how it feels
