I'm feelin sick inside
cause I can't believe it's happening
I thought that he'd be gone by now
We were on a break and you said you needed space to breathe
I didn't know your ex was in town

I finally figured it out
 [bad word] 
You're heartless
The devil in disguise
So heartless
You make me feel just like
I'm helpless, foolish, selfish, so alone
So heartless

When I asked you what happened
You sat there and lied to me
An swore you were just hangin out
So why'd you look so scared baby every time the phone would ring?
And how do you explain the stains I found?

I finally figured it out
 [bad word] #2:
You're heartless
The devil in disguise
So heartless
You make me feel just like
I'm selfish, foolish, helpless, all alone
You're heartless
There's nothing left inside but darkness
I finally realized
You're selfish, foolish, helpless, so [bad word] cold
So so heartless
Yeah yeah yeah yeah

You're heartless
The devil in disguise
So heartless
You make me feel just like
I'm selfish, foolish, helpless, all alone

You're heartless
The devil in disguise
So heartless
You make me feel just like
I'm selfish, foolish, helpless, all alone
You're heartless
There's nothing left inside but darkness
I finally realized
You're selfish, foolish, helpless, so [bad word] cold
So so heartless
