Chorus: 
                  C                       F#             C# 
It hit me like a heart attack, when you finally left me girl 
                   C 
I thought I never want you back 
    A#                                       D#m C 
But I don't wanna live in a world without you 
F#                         C#              D#m C 
I don't wanna live in a world without you 
F#                        C# 
I don't wanna live in a world without you 
 
Verse I: 
 
D#m                 C                         F#        C# 
Never really noted, all the little things you did, you did 
D#m                 C                      F#           C# 
Never bought roses, always was around my friends, my friends 
    D#m               C 
And now I'm hearing around 
      F#                 C# 
That you been running around 
D#m                         C                     F#    C# 
I didn't think I miss you, now I'm feeling like a fool 
 
Chorus 
 
Verse II: 
 
D#m                      C      F# 
Never should've let you slipped away 
              C#                    D#m 
Living in a world that's turned to grey 
              C              F#  C# 
Little did I know it hurt so bad
