Foundations by Kate Nash

I was trying to learn this song and although the verses worked out ok I found the chorus 
the tabs available just didn't sound correct.
After watching various clips of Kate Nash and her band playing live I've come up with

Chorus
F                                   Am

Amin                                    G
And every time we fight I know it's not right, every time that you're upset
      F					     G
and I smile. I know I should forget, but I can't
