Intro: 
Em G A C (2x) 

verse 1: 
Em           G 
I know what you did last night 
A                 C 
You were hanging out with that other guy 
Em                    G  
Sorry to burst your bubble but he's trouble, yeah 
A        C 
I know, I know 
Em     G 
He is my ex boyfriend 
A              C 
I thought our relationship would never end 
Em               G 
But obviously I was terribly wrong 
A         C 
Whoa-oh Whoa-oh 

Pre Chorus: 
    Em            G         D 
You don't believe me and I know you think I'm wrong 
Em           G           D              C           Em   G    D 
But when he breaks your heart you'll remember this sooooooooooooong 

Chorus: 
         Em                G         
He's a troublemaker and a heartbreaker,  
        D                        C 
he'll break your heart just like mine too. 
    Em                         G 
He doesn't even care and he doesn't understand  
      D                         C 
the feelings that we have been put through 
         Em                       G 
He will leave you in an alleyway all alone 
D                             C 
Won't even call you on the telephone. 
Em                              G 
You'll be in your room crying "Boo Hoo Hoo" 
            D 
And you're too scared because you don't  
(silence) 
know what to do. 

(single strum) 
Em Em     G G 
     Oh oh    Oh, oh 
D

C

(single strum)

verse 2: 
Em                G 
Tell me this, did he try to kiss you 
A                       C 
or even get into your pants? 
Em        G 
Oh, how predictable and despicable! 
A                        C 
Do you really call that romance? 
Em                    G 
Listen, Honey, he's a user and abuser 
          A                     C 
and he chooses girls that seem easy. 
Em             G 
You deserve a guy that treats you  
A             C 
like you're royalty.  

Pre Chorus: 
    Em            G         D 
You don't believe me and I know you think I'm wrong 
Em           G           D              C           Em   G    D 
But when he breaks your heart you'll remember this sooooooooooooong
