I saw her standing across the astroturf
Couldn't believe that you had got there first
You said you loved her, did you really though?
Already has someone else on the go

And yes, she stayed the night and she
She probably shouldn't have
Look in her eyes and tell
Tell me you wouldn't have

All is fair in matters of the heart
So go ahead and tear this friendship apart

It's not my fault
You know what's done is done
She wanted me, let it be
We were still so young

Wish I could say that: Sorry, I'm wrong
But it's not my fault that you got cheated on (ooh)

You only know a good thing when it's gone
But it's far too late to play that pity song
Maybe if you had learnt to treat her right
She wouldn't have run into my arms that night

Yes, she stayed the night and she
She probably shouldn't have
Look in her eyes and tell
Tell me you wouldn't have

All is fair in matters of the heart
So go ahead and tear this friendship apart

It's not my fault
You know what's done is done
She wanted me, let it be
We were still so young

Wish I could say that: Sorry, I'm wrong
But it's not my fault that you got cheated on (ooh)
You got cheated on (ooh)

If I were you
