It's basically, B5 , E5 , F#5 , Ab5 throughout, but the bridge is slightly different.

INTRO

B5 , E5 , F#5 , Ab5 (x2)

VERSE 1

B5     E5
So maybe I'm just blind
   F#5           Ab5
Or maybe I can't see
B5      E5
Well either one is fine
 F#5            Ab5
I speak redundantly

B5        E5
It's hard to see what's wrong
             F#5             Ab5
When you're diving in like me
   F#5      E5             F#5  F#5
I used to love relentlessly

CHORUS

    B5    E5         F#5      Ab5
So how can you remember everything?
        B5       E5
Is there a rulebook for our love
      F#5       Ab5
I'm not reading?
                  B5       E5
If we could just free up the laws
        F#5          Ab5
That bind our lives
         F#5        E5   
Then we could love
                     F#5  F#5
Yeah, we could love


VERSE 2

B5        E5
Don't get me wrong here
    F#5                  Ab5
I need you in my life
               B5           E5
But we're independent people 
F#5                  Ab5
At the current time

  B5         E5
I know that years from now
F#5                          Ab5      
The day will finally come 
      F#5    E5             F#5  F#5
for us to love perpetually

CHORUS

    B5    E5         F#5      Ab5
So how can you remember everything?
        B5       E5
Is there a rulebook for our love
      F#5       Ab5
I'm not reading?
                  B5       E5
If we could just free up the laws
        F#5          Ab5
That bind our lives
         F#5        E5   
Then we could love
                     F#5  F#5
Yeah, we could love

BRIDGE 

E5 , F#5 , F#5 , 
Eb5 , E5


E5                   F#5 , F#5 , 
This is where I draw the line this time
        Eb5 ,               E5
This just has to stop right here
E5                   F#5 , F#5 , 
If we can't just learn to live our lives
       Eb5 ,                  E5
Then we don't have any hope at all

CHORUS (BROKEN DOWN)
    B5    E5         F#5      Ab5

That bind our lives
