Couldn't find this on the internet at all and I've not even heard a guitar cover. 
I'd suggest playing along with the official song to grasp the chord changes.
Pretty sure this sounds the same, try it out, see what you think, suggest any 
changes. Cheers, AshleyColin.



Better Off as Two Chords

Chords  (B  F#  Abm F#) (Bsus4)
All Barre Chords

CHORUS

B                           	F# --Abm
I’m sorry but did I never mention
                       F#
I’m better off with you
B			          F# -- Abm
‘Cause now I think it’s time that you understood
	          F#
We’re better off as two


VERSE
B	                    F# --Abm
Ever since we met we’ve never been too clear
	  F#
All our insecurities turn up in all our fears
B	                    F# -- Abm
And how we’ve tried to make our problems disappear
	          F#
Never searching hard enough to find only more tears

PRE-CHORUS

B	  Bsus4
That’s why we are bound
Abm                     F#
The reason we are joined
B                               Bsus4
‘Cause we are always trying to be
Abm                      F#
Strongest at our weakest points

CHORUS
B                           F# --Abm
I’m sorry but did I never mention
	           F#
I’m better off with you
B                                   F# --Abm
‘Cause now I think it’s time that you understood
                      F#
We’re better off as two

VERSE

B					F# – Abm
I know it gets too much sometimes when we’re both not in tune
	               F#
Singing to a different song, breaking us both in two
B	                      F# --- Abm
Then we start again, all the mistakes that we’ve made
	              F#
Now we work in harmony with notes that never stray

PRE-CHORUS

B	            Bsus4
‘Cause we are always trying to be
Abm	            F#
Strongest at our weakest points

CHORUS

B	           F# -- Abm
I’m sorry but did I never mention
	            F#
I’m better off with you
B	                        F# -- Abm
‘Cause now I think it’s time that you understood
                      F#
We’re better off as two

VERSE

B	                  F# -- Abm
Limiting ourselves has never worked too well
	       F#
Boundaries never kept but always making more but still
B	                F# -- Abm
We have made it far in the space of time
	        F#
Being on our own won’t work so why not just be mine



CHORUS

B 	             F# -- Abm
I’m sorry but did I never mention
	          F#
I’m better off with you
B	                           F# -- Abm
‘Cause now I think it’s time that you understood
	            F#
We’re better off as two

CHORUS

B 	            F# -- Abm
I’m sorry but did I never mention
	          F#
I’m better off with you
B	                           F# -- Abm
‘Cause now I think it’s time that you understood
	           F#
We’re better off as two
