I could be really off, but this sounds very decent on an acoustic guitar to me. 
Throw a Capo on one and play these chords relevant to capo. The F#m might be 
difficult if you've never played it this way before.

Intro: A, E, B, B x2

Verse:
                          A
And I'm tearing down the walls I've made
                  E             B
To try and keep girls like you away
                  A                              E      B
But still you'll find your way right back into my heart
                     A
And am I'm the only one like this
                   E           B
That's finding it hard to be missed
                           F#m
I've been waiting here for just one kiss
              E      B
From someone else's lips

Chorus:
     A     E      B
And I'll be just fine
If you just stay here for a while
     A    E   B
And I'll be okay
If you just stay with me x2

Verse:
                        A
And I'm staying up all night again
                     E         B
Writing songs about where and when
         A                                  E    B
I could hold you 'til you rest your head to sleep
                                 A
This is the part where I should act my age
                        E      B
Go get a job and let's all get paid
                          F#m
We'll live it up 'til the end of days
        E            B        F#m
You and me, wait and see, honestly
         A
Please promise me

Chorus:
     A     E      B
And I'll be just fine
If you just stay here for a while
     A    E   B
And I'll be okay
If you just stay with me x2

Bridge:
A *ring*
Stay with me
A     B   C#m   E   
Stay With Me
A     B   C#m   E   
Stay With Me
A                      B
And all I wanted was a happy ending
C#m                 E
A better life just stay with me
A     B   C#m   E   
Stay With Me

Chorus:
     A     E      B
And I'll be just fine
If you just stay here for a while
     A    E   B
And I'll be okay
If you just stay with me
*keep repeating*
