This is a very easy song to play, and a great song of her My December album. I'm still
on the chorus but i know the intro and verses are correct. Not 100% sure on Pre-Chorus. 
whole song is just down strums. Listen to the song to know when to change chords.

Pre-Chorus:

G5Don't (355xxx@1)move, I wanna remember you just like this,

G5Don't (355xxx@1)move, it's only a breath or two between our lips.


Chorus:

I know why you left, I can't blame you myself,
Must be hard living with ghosts in such an empty shell.
I tried to warn you, been a mess since you've known me,
I can't promise forever, but I'm working on it.
If I can't hold you, can I give you a kiss?
Can I have a kiss?


Verse 2: (Same chords as verse 1)

I see that you're torn, I've got some scars of my own,
Seems I want what I know is gonna leave me hungry

Pre-Chorus:

G5Don't (355xxx@1)move, I need to remember you just like this.


Chorus:

I know why you left, I can't blame you myself,
Must be hard living with ghosts in such an empty shell.
I tried to warn you, been a mess since you've known me,
I can't promise forever, but I'm working on it.
If I can't hold you, can I give you a kiss?
Can I?

All I have, all I can
Give to you I will, just promise this
If I can't have forever,
Can I have a kiss?

I know why you left, I can't blame you myself,
Must be hard living with ghosts in such an empty shell.
I tried to warn you, been a mess since you've known me,
I can't promise forever, but I'm working on it.
If I can't hold you, can I give you a kiss?
Can I give you a kiss?
Can I, can I
Can I have a kiss?"
