Hi, I just wanted to correct some things from the 1st version.
My first tab, so let me know what you think!
Rate and comment~ :)

Taylor's voice is kinda high, so if you wanna bring it down to suit your voice, 
just move the capo down or remove it completely.

Capo on 4th
(Standard tuning)

* = single strum


Intro
D


D                  
Once upon a time, a few mistakes ago
A
I was in your sights, you got me alone
Bm                                G
You found me, you found me, you found me-e-e-e-e

D
I guess you didn't care, and I guess liked that
    A
And when I fell hard, you took a step back
    Bm                    G
Without me, without me, without me-E-E-E-E


D                A                      Bm
   And he's long gone, when he's next to me and I 
       G          (pause)
Realize the blame is on me



       Bm*                G*                   A*
'Cause I knew you were trouble when you walked in
         D      A   Bm
It's a shame on me now-ow
(Bm)       G*                A*
Flew me to places I'd never been 
           D       A
'Till you put me down, oh
Bm              G                       A
I knew you were trouble when you walked in 
         D      A   Bm
It's a shame on me now-ow
(Bm)       G                 A
Flew me to places I'd never been
        D -mute                 Bm
Now I'm lyin' on the cold hard ground!

(Bm)  Em    A         D        A      Bm 
Ahh     oh, trouble, trouble, trouble
(Bm)  Em    A         D        A
Ahh     oh, trouble, trouble, trouble



D
No apologies, he'll never see you cry
   A
Pretends he doesn't know, that he's the reason why
       Bm                                  G 
You're drowning, you're drowning, you're drowning-e-e-e-ing

        D
Now I heard you moved on, the whispers on the street
    A
A new notch in your belt, is all I'll ever be
    Bm                      D
And now I see, now I see, now I see-e-e-e-e


D                A              Bm
   He was long gone, when he met me
              G                      G* (pause)
And I realize, the joke is on me,  yeah



Bm              G                       A
I knew you were trouble when you walked in
         D      A   Bm
It's a shame on me now-ow
(Bm)       G                A
Flew me to places I'd never been 
           D       A
'Till you put me down, oh
Bm              G                       A
I knew you were trouble when you walked in 
         D      A   Bm
It's a shame on me now-ow
(Bm)       G                 A
Flew me to places I'd never been

Ahh     oh, trouble, trouble, trouble

Ahh     oh, trouble, trouble, trouble


        Em*                   Bm*
And the saddest fear, comes creepin' in
         Em*
That you never loved me, or her, 
   A*         G*        A
Or anyone, or anything, yeah yeah
