I watched you, walk into the room I watched you, while he was kissing you
And now it's he said, she said, tell me the truth
You know I saw you, caught you, knew what you do
You know I watched you, doing what you do
You told me I'm the one
I hope you had your fun
I'm done and I want out of this
Heart attack, heart attack
I'm never gonna take it back, take it back
I'm never gonna break, I'll show you
I won't call you
Heart attack, heart attack
I'm never gonna live with that, live with that
My nightmare just came true
And now the heart attack's on you
Do you miss me, when you close your eyes?
Do you still see, me in his disguise?
And now it's he said, she said, tell me the truth
She said all of the lies
You know I saw you, caught you, what is the prize?
Do you miss me, I'm kissing you tonight
You told me I'm the one
I hope you had your fun
I'm done and I want out of this
Heart attack, heart attack
I'm never gonna take it back, take it back
I'm never gonna break, I'll show you
I won't call you
Heart attack, heart attack
I'm never gonna live with that, live with that
My nightmare just came true
And now the heart attack's on you
And now the heart attack's on you
I'm out the door and you're barely breathing
Now I'm leaving you
You really should've thought things through
I guess I wish you all the best
As long as your heart breaks in two
Heart attack, heart attack
I'm never gonna take it back, take it back
I'm never gonna break, I'll show you
I won't call you
Heart attack, heart attack
I'm never gonna take it back, take it back
I'm never gonna break, I'll show you
I won't call you
Heart attack, heart attack
I'm never gonna break, I'll show you
I won't call you
My nightmare just came true
And now the heart attack's on you
Heart attack, heart attack
