I added a little spice into it.

Verse 1:
D/F#                                     Asus2
I'm scrolling through my cellphone for the 20th time today
Em7
I'm reading that text you sent me again 
G
Though I memorized it anyway

D/F#        
It was an afternoon in December 
          Asus2
When it reminded you of the day 
               Em7
When we bumped into each other 
        G
But you didn't say Hi cuz I looked away

Pre-Chorus
Em7                       D/F#               G
And maybe that was the biggest mistake of my life
Em7                      D/F#             Asus2
And maybe I haven't moved on since that night

Chorus:
D                              Asus2
Cause it's 12:51 and I thought my feelings were gone 
             Em7                    G
But I'm lying on my bed thinking of you again
        D                              Asus2
And the moon shines so bright but I gotta dry these tears tonight
      Em7                                              G
Cause you're moving on and I'm not that strong to hold on any longer

Interlude:
  D#F  Asus2   Em7   G
Oh oh   oh    woaah oh oh oh..

Verse 2:
Then I saw you with her
Didn’t think youd find another
And my world just seem to crash
I shouldnt have thought that this would last

Pre-Chorus:
And maybe that was the biggest mistake of my life
Maybe I haven’t moved on since that night

Cuz its 12:51 and I thought my feelings were gone
But I’m lying on my bed Im thinkin o you again
And the moon shines so bright
But I gotta dry these tears tonight 
Cuz youre moving on and I’m not that strong to hold on
Any longer 

Bridge:
Em7                       G
  As the sky outside gets brighter
                     D/F#
And my eyes begin to tire
           Asus2
Im slowly drowning in memories of him
Em7                       G
  And I know it shouldnt matter
                      D/F#
As my heart begins to shatter
            Asus2              G* (once)
Im left to wonder just how it should have been yeaah

[Pause]

Spoken: *use chords for verse & strum lightly*
Hey Tony I just wanted to say thanks for showing me around
I really had a great time. I wish that I didn’t have to leave but 
I wont forget about you.

Last Chorus:
twelve fifty-one and I thought my feelings were gone
But Im lying on my bed 
I’m not thinkin of you again
And the moon shines so bright
But I gotta dry these tears tonight
Cuz you’re moving on and Im not that strong to hold
Cuz Ill prove you wrong that I can move on through this song
Im so much stronger ohhh woaaah woaaah ohhh ooooh oh.
