Give Your Heart A Break- By Demi Lovato
I adore this song so I wanted to do a simple tab for beginners.
I didn't use any bar chords so it's pretty easy. 
It's not exactly how it sounds on the track but it sounds pretty accurate.

Verse 1:
G         D
The day I first met you
A         C
You told me you'd never fall in love
G            D
But now that I get you
A         C
I know fear is what it really was

Prechorus:
G                 D           
Now here we are, so close
A         C
Yet so far, haven't I passed the test?
G             D-C
When will you realize
A-stop
Baby, I'm not like the rest

Chorus:
G
Don't wanna break your heart
D
I wanna give your heart a break
A
I know you're scared it's wrong
C
Like you might make a mistake
G
There's just one life to live
D                            A
And there's no time to waste, to waste
C
So let me give your heart a break
G
Give your heart a break
D
Let me give your heart a break
C
Your heart a break

A
Oh, yeah yeah

Verse 2:
G          D            A
On Sunday, you went home alone
C
There were tears in your eyes
G             D          C
I called your cell phone, my love
A
But you did not reply

Prechorus 2:
G                  D
The world is ours, if you want it
A                 C
We can take it, if you just take my hand
G              D        C
There's no turning back now
A- Stop
Baby, try to understand

Chorus:
G
Don't wanna break your heart
D
I wanna give your heart a break
A
I know you're scared it's wrong
C
Like you might make a mistake
G
There's just one life to live
D                            A
And there's no time to waste, to waste
C
So let me give your heart a break
G
Give your heart a break
D
Let me give your heart a break
C
Your heart a break


Bridge:
G                    A
When your lips are on my lips
D                    G
And our hearts beat as one
         Bm                      A
But you slip right out of my fingertips
D             G-D-C-A
Every time you run, whoa

Chorus: x2
G
Don't wanna break your heart
D
I wanna give your heart a break

I know you're scared it's wrong
C
Like you might make a mistake
G
There's just one life to live
D                            A
And there's no time to waste, to waste
C
So let me give your heart a break
G
Give your heart a break
D
Let me give your heart a break
C
Your heart a break

A
Oh yeah, yeah

G         D
The day I first met you
Bm         A
You told me you'd never fall in love
