Capo 3 :)
This is easy to play and I think it sounds accurate
This is my first tab!
Most of the song the chord progression is G, D, Em, C (until the bridge)
I use the strumming pattern D,D,U,U,D , its not accurate but it fits, use 
whichever strumming works for you!

            G
You call me up,
                  D
Its like a broken record
                 Em
Saying that your heart hurts
            C
Thought you'd never get over him getting over you,
G              D
And you end up crying
             Em
And I end up lying,
      C
Cause I'm just a sucker for anything that you do,

G                                D
And when then phone call finally ends,
                            Em
You say "thanks for being a friend"
And I'm going in circles again and again. 

G                       D
I dedicate this song to you
                           Em
The one who never sees the truth
                          C
That I can take away your hurt, Heartbreak girl
G                            
Hold you tight straight through to day light,
D                                     Em                 C
I'm right here when you gonna realise that I'm your cure Heartbreak girl,

          G                  D
I bite my tongue but I wanna scream out
                Em
You can be with me now
    C                                   G
But I end up telling you what you wanna hear,
               D                     Em
But you're not ready and its so frustrating
   C
He treats you so bad and I'm so good to you its not fair.

G                               D
And when the phone call finally ends
                                 Em
You say ill call you tomorrow at 10
And I'm stuck in the friend zone again and again,

G                       D
I dedicate this song to you
                           Em
The one who never sees the truth
                          C
That I can take away your hurt, Heartbreak girl
G                            
Hold you tight straight through to day light,
D                                     Em                 C
I'm right here when you gonna realise that I'm your cure Heartbreak girl,

F                        C
I know someday its gonna happen
           G                          D 
And you'll finally forget the day you met him
F                               C
Sometimes we're so close to preventing
        G                                   D
I gotta get it through your head that you belong with me instead,

G                       D
I dedicate this song to you
                           Em

That I can take away your hurt, Heartbreak girl
G                            
Hold you tight straight through to day light,
D                                     Em                 C
