It's a really good song but I can't find the chords anywhere on the internet so 
here goes... It's featured on the episode 18, season 1 of "How I Met Your Mother", 
right at the very end.

Tuning: Standard, Capo on 1st Fret

Verse 1
D            A              Bm          D
Sorry Baby but its getting too much to take
D            A              Bm          D
I close my eyes I know my hearts about to break
E                  F#m
I'm down on my knees tryin to pick myself up
D            A          Bm          D
When the battles over, seems nothings not enough


Verse 2
D            A              Bm          D
The way you do me, you know it hurts me to the bone
D            A              Bm          D
How you touch me, I'd be better off alone
E                  F#m
Sayin I'm sorry till I'm blue in the face
D            A              Bm          D
Leaves me empty with no love left to waste

Pre-chorus
Bm          F#m          Bm            F#m
We promise to have, oh we promise to hold
Bm                  A
How does a promise ever grow old

Chorus
D            A          Bm          D
So listen baby, I'm gonna get back on my feet
D            A          Bm          D
Tuck this old shirt in and wipe the crimson off my cheek
E                  F#m
Remember these secrets were all that I kept
D            A          Bm          D
When I pull out this driveway and hang a Hard Left


Pre-chorus
Bm          F#m          Bm            F#m
We promise to have, oh we promise to hold
Bm                  A
How does a promise ever grow old
