At the end of the video, she welcomes him back home as if nothing had happened

You and me we made a vow
for better or for worse
I can't believe you let me down
but the proof is in the way it hurts

For months on end I've had my doubts
denying every tear
I wish this would be over now
but I know that I still need you here

You say...I'm crazy
cause you don't think I know what you've done
But when...you call me baby
I know I'm not the only one

You've been so unfaithful
now sadly I know why
Your heart is unobtainable
even though you don't share mine

You say...I'm crazy
cause you don't think I know what you've done
But when...you call me baby
I know I'm not the only one

I have loved you for many years
maybe I am just not enough
You've made me realise my deepest fear
by lying and tearing us up

You say...I'm crazy
cause you don't think I know what you've done
But when...you call me baby
I know I'm not the only one
You say...I'm crazy
cause you don't think I know what you've done
But when...you call me baby
I know I'm not the only one
I know I'm not the only one
I know I'm not the only one
And I know...
And I know...
And I know...
And I know...
And I know...
And I know...
I know I'm not the only one
