Look at you
Over there, over me with someone new
It's like he fixed your heart with superglue
So fast, I'm so mad at how happy you are now

There you go
Actin' like nothin' ever happened, don't you know
How hard that it's been for me to let you go?
Oh my God, I'm so sick of seein' you out

Smilin' in pictures
Like you've never been better
Just throwin' it all in my face

It's killin' me
Tell me why you gotta bring out all my jealousy?
Baby, you don't even treat me like an enemy
We're done, we're through
Yeah, it's just killin' me
How much it's not killin' you
How much it's not killin' you

I wish you would
Stop tellin' all my friends you're doin' good
'Cause, I still miss you more than I probably should
So, pump the breaks, I'm movin' on
'Cause you never cared about me, no, you never did

It's killin' me
Tell me why you gotta bring out all my jealousy?
Baby, you don't even treat me like an enemy
We're done, we're through
Yeah, it's just killin' me
How much it's not killin' you
How much it's not killin' you

Can't you have a little decency
And maybe try to be a little less over me
Do you even cry
Lose any sleep at night
'Cause you're really convincin'
How much you're livin' your life

And it's just killin' me
Tell me why you gotta bring out all my jealousy
Baby, you don't even treat me like an enemy
We're done, we're through
Yeah, it's just killin' me
How much it's not killin' you
How much it's not killin' you

(How much it's not killin' you, yeah)
How much it's not killin' you
