Let me tell you something
Never have I ever been a size 10 in my whole life
I left the engine running, I just came to see,
What you would do if I, gave you a chance to make things right.

So I made it even though Katie told me 
That this would be nothing but a waste of time, 
And she was right.
Hmm, don't understand it blood on your hands
And still you insist on  repeatedly trying to tell me lies 
And I just don't know why.

Oh, this is stupid, I'm not stupid
Don't talk to me like I'm stupid
I still love you, but I just can't do this
I may be dumb, but I'm not stupid

My new nickname is "you idiot" (such an idiot)
Hmm, that's what my friends are calling me 
When they see me yelling into my phone, 
They're telling me let go, he is not the one.
I thought I saw your potential,
Guess that's what made me dumb.

He don't want it, not like you want it, scheming and cheating, 
Oh girl why do you waste your time?
You know he ain't right. 
You're telling me this, I don't wanna listen.
But you insist on repeatedly trying to tell me lies 
And I just don't know why.

This is stupid, i'm not stupid
Don't talk to me like i'm stupid
I still love you but I just can't do this
I may be dumb but i'm not stupid

Trying to make this work
But you act like a jerk
Silly of me to keep holdin' on

But the dunce cap is off
You don't know what you've lost
And you won't realize till I'm gone, gone, gone...

That I was the one, which one of us is really dumb
No, no, no, I'm not stupid in love

This is stupid, I'm not stupid
Don't talk to me like I'm stupid
I still love you but I just can't do this
I may be dumb but I'm not stupid
