[Intro]
Am          C 
 Heartless, (heartless, heartless) 
G                  D 
 so heartless, (so heartless, so heartless)
[Strophe]
Am 
 Say you goin' out late 
C 
 I count down till you call me 
G                            D 
 It's just one of those things 
                             Am 
That you do when you're lonely 
                            C 
And you're all about the chase 
                                  G 
But you won't ever let me catch you 
                        D 
And I wish I was the same 
  
But I know I'm gonna let you 
Am 
Win again and when I do 
     C 
It's gonna hurt like Hell 
              G 
And you don't mean to 
                     D 
That's what I tell myself
[Refrain]
                        Am 
But why you gotta be so heartless? 
                      C 
I know you think it's harmless 
                     G 
You're tearing me apart and 
                   D 
Girl, the hardest part is 
                    Am 
You're so high on attention 
                 C 
Taking miles for inches 
                  G 
Leave me in the darkness 
                       D 
Never finish what we started 
                          Am 
Girl, why you gotta be so heartless? 
C                     G         D 
  Why you gotta be so heartless?
[Strophe]
Am 
Monday night was definitely not our night 
C 
Tuesday night was just another fight 
G 
Wednesday, I thought everything would change 
D 
Thursday came and it was still the same 
Am 
Friday night, we went out on the town 
C 
Saturday, we should have burned it down 
G 
Sunday morning came and now you're gone
