This song is a little tricky to play, and likewise a bit tricky to explain. So I'm going to format this in a 
way that is as easy to understand as possible.

Since There are a LOT of chords(note they are mostly variations of the same chords around their respective
scale), I'll split them up into the intro ones, then the others.

I would HIGHLY recommend learning these first, and getting comfortable with moving your hand around the 
chord progression below. Before you even look at the tab.

Chord Progression [Intro]

Ab9     G#m9    Db13       
Woah,   Woah,   Woah

             Db6(11)
I  want  to  know

               Db6sus
Where  I  can  go

                    Bmaj7  
When  you're  not  around
                
                   Bbm7
And  I'm  feeling  down

    Dm          Bmaj7
So  won't  you  stay 

      Cm7(b5)
for a moment?

         Bmaj7
So I can say...

(The Chords are repeated a second time, with the new lyrics to finish the intro)

That I,  I, oh I
That I need you so
'Cause right now you know
That nothing here's new
And I'm obsessed with you

Then I fell to the ground
And you smiled at me 
and said...


Once you have that down. Here's the version that integrates the chords with every note played. For how the 
song sounds when recorded and performed.

Chord Progression [Verse/Chorus/Bridge]

                              Db6(11)
I  don't  want  to  see  you  cry 

                     D#m7(b5)        Ab6(11) 
you  dont  have  to  feel  this  emptiness.

              Fm7(b5)                              D#dim  D#m7(b5)  
She  said  I  love  you  'till  the  day  that  I  Die  

     G#m7(b5)   Db6(11)        
Well maybe Shes Right... 

                     D#m7(b5)          Ab6(11)
'Cause I don't wanna feel like I'm not me

          Fm7(b5)                  D#dim
And to be honest I don't even know why

D#m7(b5)                      G#m7(b5) Db6(11)
I let myself get down in the first place

(this progression repeats until the end of the song, even through the bridge. Rex randomly finger picks 
portions of the chords. So play around to get the right sound you want!)
