My first tab and I did it all by ear so hopefully it sounds close to the original 

Standard tuning
 
[Verse 1] (Fm, C#, Ab, Eb)
Fm                  C#                        Ab
What would I do without your smart mouth
            Eb                 Fm
Drawing me in, and kicking me out
          C#           Ab               Eb          Fm
Got my head spinning, no kidding, I cant pin you down
             C#                     Ab
Whats going on in that beautiful mind
               Eb             Fm
Im on your magical mystery ride
        C#             Ab                     Eb         Bbm
And Im so dizzy, dont know what hit me, but Ill be alright

[Bridge] (Bbm, Fm, Eb)
Bbm              Fm
My heads under water
    Eb             Bbm
But Im breathing fine
                Fm             Eb
Youre crazy and Im out of my mind

[Chorus] (Ab, Fm, Bbm, Eb)
       Ab
Cause all of me
       Fm
Loves all of you
            Bbm
Love your curves and all your edges
           Eb
All your perfect imperfections
           Ab
Give your all to me
            Fm
Ill give my all to you
         Bbm
Youre my end and my beginning
      Eb
Even when I lose Im winning
                  Fm   C#     Ab
Cause I give you all, all of me
                 Fm   C#      Ab    Eb
And you give me all, all of you, oh

[Verse] (Fm, C#, Ab, Eb)
Fm              C#                 Ab
How many times do I have to tell you
                  Eb                     Fm
Even when youre crying you?re beautiful too
              C#           Ab         Eb                  Fm
The world is beating you down, Im around through every move
            C#                Ab
Youre my downfall, youre my muse
             Eb                        Fm
My worst distraction, my rhythm and blues
               C#            Ab        Eb            Bbm
I cant stop singing, its ringing, in my head for you

[Bridge] (Bbm, Fm, Eb)

[Chorus] (Fm, C#, Ab, Eb)

[Bridge Change]
Bbm            Fm
Cards on the table
       Eb             Bbm 
Were both showing hearts
Am          Fm               Eb
Risking it all, though its hard

[Chorus]
                  Fm   C#      Ab
Cause I give you all, all of me
                 Fm   C#      Ab    Eb
And you give me all, all of you, oh
