I should have known by the way you passed me by
There was something in your eyes and it wasn't right
I should have walked but I never had the chance
Everything got out of hand and I let it slide

Now I only have myself to blame for falling for your stupid games
I wish my life could be the way it was before I saw your face

You stole my happy, you made me cry
Took the lonely and took me for a ride
And I wanna uh-uh-uh-uh-uh-undo it

You had my heart, now I want it back
I'm starting to see everything you lack
Boy, you blew it, you put me through it
I wanna uh-uh-uh-uh-uh-undo it

Na, na, na, na, na
Na, na, na, na, na
Na, na, na, na, na, na

Now your photos don't have a picture frame
And I never say your name and I never will
And all your things, well I threw them in the trash
And I'm not even sad

Now you only have yourself to blame for playing all those stupid games
You're always gonna be the same and, oh no, you'll
never change

You stole my happy, you made me cry
Took the lonely and took me for a ride
And I wanna uh-uh-uh-uh-uh-undo it
You had my heart, now I want it back
I'm starting to see everything you lack
Boy, you blew it, you put me through it
I wanna uh-uh-uh-uh-uh-undo it

Na, na, na, na, na
Na, na, na, na, na
Na, na, na, na, na, na

You want my future, you can?t have it
I'm still trying to erase you from my past
I need you gone so fast

You stole my happy, you made me cry
Took the lonely and took me for a ride
And I wanna uh-uh-uh-uh-uh-undo it
You had my heart, now I want it back
I'm starting to see everything you lack
Boy, you blew it, you put me through it
I wanna uh-uh-uh-uh-uh-undo it

You stole my happy, you made me cry
Took the lonely and took me for a ride
Boy, you blew it, you put me through it
I wanna uh-uh-uh-uh-uh-undo it
