okay this is like 95% right. i had to figure out the whole thing, especially the bridge. 
if u know whats right just tell me!


play the chords like this (fret number from low E to high E):
G   320033
C7  x32033
Em  022000
D   x00232
Am  x0221x

BUT for the chorus play G and C differently:
G   320003
C7  x3203x


G               C7
    Told you I made dinner plans
G               C7
    You and me and no one else
G                     C7
    It don't include your crazy friend
          Em
Well I'm done
             D                 C7          Am
With awkward situation's empty conversations


Em            C7
Oh This is an S.O.S.
             G
Don't wanna second guess,
            D
This is the bottom line
      Em
It's true
          C7
I gave my all for you,
       G
now my heart's in two
      D                    Am
And I can't find the other half
               C7               G
It's like I'm walking on broken glass,
       D
better believe I bled
Am           C7
      It's a call I'll never get


G                       C7
   So this is where the story ends
G                 C7
   A conversation on IM
         Em
Well I'm done

Texting,
D                      C7     Am
Sorry for the miscommunication


Em            C7
Oh This is an S.O.S.
             G
Don't wanna second guess,
            D
This is the bottom line
      Em
It's true
          C7
I gave my all for you,
       G
now my heart's in two
      D                    Am
And I can't find the other half
               C7               G
It's like I'm walking on broken glass,
       D
better believe I bled
Am           C7
      It's a call I'll never get


Em         C7
      Next time I'll see you
G                         D
    I'm giving you a high five
      Am                        D
cause hugs are over rated, just FYI


Em            C7
Oh This is an S.O.S.
             G
Don't wanna second guess,
            D
This is the bottom line
      Em
It's true
          C7
I gave my all for you,
       G
now my heart's in two (yeah)


Em            C7
Oh This is an S.O.S.
             G
Don't wanna second guess,
            D
This is the bottom line
      Em
It's true
          C7
I gave my all for you,
       G
now my heart's in two
      D                    Am
And I can't find the other half
               C7               G
It's like I'm walking on broken glass,
       D
better believe I bled
Am           C7
      It's a call I'll never get
