Everyone at school thought we were sisters
Dressed the same, talked the same, together all the time
You could find me in your family pictures
Next to you, in the frame, but you moved on and I'm replaced

I only wanted you to be happy
But I never thought it'd be without me

Ooh-ooh, now you don't know me at all
You left with no warning
Always thought that it'd be love
That was gonna mess me up
Didn't think this it'd hurt this much
When best friends break up

You don't evеn seem upset about it
Guess I'm the onе who lost the things
You had all the time
You seem like you're cool with or without it
'Cause you put me through hell
Just to have someone else

I hope he always makes you happy
But why did it have to be without me?

Ooh-ooh, now you don't know me at all
You left with no warning
Always thought that it'd be love
That was gonna mess me up
Didn't think this it'd hurt this much
When best friends break up, break up
I just
Always thought that it'd be love
That was gonna mess me up
Didn't think this it'd hurt this much
When best friends break up
Ooh-ooh, now you don't know me at all
You left with no warning
Always thought that it'd be love
That was gonna mess me up
Didn't think this it'd hurt this much
When best friends break up
