This song is a LOT easier than they make it out to be.

Intro chords:
C, Am, F, Dm x2

Verse: 
C, G, Em, Am, F, Dm, C, B flat, Am, 
F
Now that I can see you
G
I don't think you're worth a second glance

Chorus:
C,      Dm,          C,          B flat x4
So much for all the promises you made

All the rest of the song is the same as the intro... 
C, Am, F, Dm

Very simple.

You called to say you wanted out
Well, I can't say I blame you now
Sometimes you've got to fold
before you're found out
Well thanks for waiting this long 
to show yourself

Cause now that I can see you
I don't think you're worth a second glance

So much for all the promises you made,
they served you well
Now you're gone and they're wasted on me

So much for your endearing sense of charm
it served you well
Now it's gone and you wasted it on me

You called to say you wanted out
Well, I can't say I blame you now
Sometimes you've got to fold
before you're found out
Well thanks, thanks for waiting this long 
to show yourself
show yourself

cause now that i can see you
i don't think you're worth a second glance

So much for all the promises you made,
they served you well
Now you're gone and they're wasted on me

So much for your endearing sense of charm
it served you well
But now it's gone and you wasted it on me

I guess that all you've got
Is all you're gonna 
so much for, so much more..

I guess that all you've got
Is all you're gonna get
So much for, so much more

Do what you must
If that's what you wish
I can't be a party to this
You have sense that you were born with
You'll find a way to make things right

I guess that all you've got
Is all you're gonna get
So much for, so much more (x3)
