I tabbed this from a demo/live version of the song. Sorry, I can't find a youtube version of it.
If you're not listening to the demo/live version, the E in the chorus is an Em.

Chords used: C, F, G, E, Em, Am
Intro: C F C (x2)

C                F                 C
I've been on the look out for some love
       C                     F            C
I have searched the planet's corners from above
       F         C            E           Am
I have opened my eyes, I have opened them wide
        F             G           C        F C
Just in case somebody takes me by surprise

         C           F                      C
And when sometimes I believe I've found the one
       C                 F           C
She'll remind me we were only having fun
          F               C               E                Am
Yeah they tell me all the time that's the biggest fault of mine
     F               G            C      F C
I'll remain in the position I'm assigned


CHORUS:
E (or Em )       Am
You can break my heart,
E                Am
You can break my heart,
        F                 G               C    F C
Just be sure that you are sure when you depart


Oh we took a little weekend by the sea
You were lovely, I was happy, we were free
And we didn't tell a soul, we let the magic just unfold
How it rolled, how it rolled, how it rolled

And I was gonna go away with you to France
You said I know it, like the back of my own hand
We can train the River Thames for a cafe on the Seine
But then this is now & that was way back then 

CHORUS:
You can break my heart,
You can break my heart,
Just be sure that you are sure when you depart


You said I'd picked my moments really really good
You jumped out of bed in front of me you stood
& you shouted me down in my dark blue dressing gown
& you turned your back and never turned around

Well there's no use trying to change somebody's heart
It will only pull your own further apart
I will just shut my eyes, I will shut them really tight
& I'll say "I know, this is only part of life."

CHORUS:
You can break my heart,
You can break my heart,
Just be sure that you are sure when you depart
