I thought the name of this song was:
THIS IS WHY WE CAN'T BE FRIENDS

Also, If you could provide the lyrics to the song here I can 
do this for you. I can not find the lyrics anywhere on the internet.

DON CZARSKI I just put "We Can't Be Friends" as the title because that's what she said in the video. Here are the lyrics

  
We Can’t Be Friends
Capo on 5th 
I know we said we wouldn’t do this, we wouldn’t go here anymore 
Empty bottles on the nightstand, all the covers on the floor
But here we are again on a Sunday mornin’
We pretend it didn’t happen, I grab my bag and head out the door
Chorus 
This is why you can’t call me up; this is why we can’t be alone
This is why we can’t drink wine cause when I’m with you I can’t say no
Say that we wouldn’t, know that we shouldn’t cause this is how it always ends
Baby this is why we can’t be friends
We had some good times before it all went wrong
And now were pretty good liars when we said we moved on
We’re like any ol’ cliché when you look at me that way
We’re right back to kissing, goodbye inhibitions so much for being strong
Chorus 
This is why you can’t call me up; this is why we can’t be alone
This is why we can’t drink wine cause when I’m with you I can’t say no
Say that we wouldn’t, know that we shouldn’t cause this is how it always ends
Baby this is why we can’t be friends
-Instrumental- 
Chorus
Baby this is why we can’t be friends

I did my chord version based on another you tube video I found

 ;

I see him capoed at the 5th fret as you mentioned..... however,
I found it best to capo at the 4th fret as the chord are easier to play
and people are more familiar with.... i also left the chords 
without a capo as well....so if you want to capo at the 5th fret then
just transpose the chords accordingly.....

Please take the time to rate this 5 stars for me ....
