I figured this out by ear... apologies if it's wrong, and apologies for leaving 
out the instrumentally parts. But you should be able to work it out yourself, with a bit of luck.

                       B
Let me start by saying sorry
               A
I know I don't tell you how I feel
           E
It takes enough to say I want you
but that's not what you need
        B
I care about you
             A
but love's a much stronger word
       E
and "I like you" really doesn't sum up
how much you're worth

A                                       E
I'm the last straw on the camel's back away
                        B
from saying those three words

                              A
I'm putting a message in this song
                         E
and I'll get everyone to sing along
B                         A
Just to let you know how I feel
E
A valentine on mp3
yours forever,
               B
less than three

[E]        B
You know I miss you
            A
when my connection goes down
      E
and I can't see your face to make it seem
like you came around
                   B
Those days without you
          A
I find it harder to sleep
       E
Even a half bottle of morgan's
couldn't make me complete

A                                                E
I'm the hair on the back of your neck's breadth away
                        B
from saying those three words

                              A
I'm putting a message in this song
                         E
and I'll get everyone to sing along
B                         A
Just to let you know how I feel
E
A valentine on mp3
yours forever,
               B
less than three

                                                 A
Take the distance from the depths of the deepest ocean
                 E
to the surface of pluto
                                  A
and multiply by as far as you can count
           E
and you'll still be nowhere near
you'll still have no idea
how much I want to hold you

B                             A
I'm putting a message in this song
                         E
and I'll get everyone to sing along
B                         A
Just to let you know how I feel
E
