Cm        Bb       Ab
We've reached the climax   
                    Eb           Cm
We're together, now we're undone
                   Bb
Won't commit so we choose to

Repeat Chords throughout song

Another way to play:
CAPO 8th Fret
    C   G       Em     D
Run away, do we separate
      C
Don't wanna give in
      G
So we both gave up
E
Can't take it back
D
It's too late we've reached the climax, climax...
