Basically, the exactly the same as version 1, but with B flat written as Bb so 
that it can be transposed for use with a capo if needed :)
F
I could have been easier on you 
                   C                Dm
I could have been all you held on to
          C       Bb                       C 
I know it wasn't fair, I tried my best to care 
        F
about you 
F
I know I could have been a better man
                   C                  Dm
But I always had to have the upper hand
           C       Bb                        C
I'm struggling to see   the better side of me

pre-chorus
Dm                                      C  
But I cant take all your jabs and taunts
Bb                                C 
Your pointing out my every fault
 Dm                                    C  
And you wonder why I walked away

chorus
F                                                  C
When you tell me I'm a wreck, you say that I'm a mess
                Dm                 Bb
How could you expect anything less
F                            C                   Bb
You latched on to me then cried I strung you along
F                                                  C
I told you when you asked, I knew this wouldnt last
                    Dm              Bb
At least I could be honest about that
F                               C                      Bb 
And now you're telling everyone how I only did you wrong

I guess you never knew me at all

F             C

verse 2 
F               
Remember on my 21st birthday 
                     C                    Dm
You took me where we went on our first date
        C            Bb                                C
we stayed till closing time, after four glasses of wine
F  
You started with a pointless argument
               C                 Dm
Said that I forgot to compliment
               C            Bb                                C
The dress you wore that night, that I've seen a thousand times

pre chorus
Dm                                        C
But I think we just want different things
Bb                                     C
I want space, you want a diamond ring
Dm                                               C
Whatever made you think we were meant to be?

chorus
F                                                  C
When you tell me I'm a wreck, you say that I'm a mess
                Dm                 Bb
How could you expect anything less
F                            C                Bb
You latched on to me then cried I strung you along
F                                                  C
I told you when you asked, I knew this wouldnt last
                    Dm             Bb
At least I could be honest about that
F                               C                    Bb
And now you're telling everyone how I only did you wrong

I guess you never knew me at all

But still I see you standing there waiting around for me to fall
F                               C                     Bb
Girl you must be crazy still believing you and me belong

I guess you never knew me at all
