Hi my name's Jerome. I love One Direction and this song is just amazing. So thanks 
Ed. This is the first tab I've ever made so bear with me :) 

Verse 1:
G
Your hand fits in mine
G
Like it's made just for me
    D
But bear this in mind
D
It was meant to be
    C
And i'm joining up the dots
C
With the freckles on your cheeks
      D                    G
And it all makes sense to me

G
I know you've never loved
G
The crinkles by your eyes
             D
When you smile,

You've never loved
D
Your stomach or your thighs
    C
The dimples in your back
C
At the bottom of your spine
         D                 G
But i'll love them endlessly

CHORUS:
Am                           C
   I won't let these little things
     G              D
Slip out of my mouth
         Am
But if I do
       C
It's you
          G 
Oh it's you
             D
They add up to 
              Am
I'm in love with you
C                            G
   And all these little things

Verse 2:
G
You cant go to bed
G
Without a cup of tea
    D
And maybe that's the reason
D
That you talk in your sleep
     C
And all those conversation
C
Are the secrets that I keep
D                            G
Though it makes no sense to me
G
I know you've never loved the sound of your voice tape
    D
You know want to know how much weigh
    C
You still have to squeeze into your jeans
      D                G
But you're perfect to me

CHORUS:
Am                           C
   I won't let these little things
     G              D
Slip out of my mouth
         Am
But if it's true
       C
It's you
          G 
Oh it's you
             D
They add up to 
              Am
I'm in love with you
C                            
   And all these little things

Bridge:
Am                C
   You'll never love yourself
       Em                D
Half as much as I love you
Am              C                       Em
  You'll never treat yourself right darlin'
                D
But I want you to
Am              C
  If I let you kno-o-o-w
    Em         D
I'm here for you
Am               C                Em        D
  Maybe you'll love yourself like I love you
Oh..

Am                                   C
 And I've just let these little things
        G           D
Slip out of my mouth
              Am
'cause it's you
          C
Oh it's you
        G
It's you
             D
They add up to
                 Am
And i'm in love you
C                           
  And all these little things

CHORUS:
Am                           C
   I won't let these little things
     G              D
Slip out of my mouth
         Am
But if it's true
       C
It's you
          G 
it's you
             D
They add up to 
              Am
I'm in love with you
C                            G
   And all these little things
