[Verse 1]
C                            Em
When I was younger, I wanted everything
G                           C
When I met you, I needed it always
C                            Em
I didn't miss you until you went away
            G              C
What did I do, what did I do?
                     Am   
I don't know how to say this
                        C
And you're not all that patient
                Em                D
Ever since you left, I've been alone
                      Am
I don't know how this happened
                  C
I got so distracted
                    Em
And now you're with someone
I know I was wrong
                      Am C Em D
Why'd I let you go?
                      Am C Em D
Why'd I let you go?
                      Am C Em D
Why'd I let you go?

[Verse 2]
C                                      Em
You say you want it all, and me I just ignore
Like I never was involved
                 G
And now I see my bullshit, I could've given more
                    C
I'm sick of all the weak shit, I've said it all before
            C
But it's alright that I was wrong
            Em                            G
And I won't fight but won't move on now, no
Shadows of you in my home
C
But now that you're gone, I'm alone
Am
Because I'm sorry for the way that it ended
C
I'm trying to see if we can mend it
Em
Sorry for the time we spent on
D
Wishing I was someone else
Am
But I've been working on myself
C                                  Em
And I've been seeing no one else, no
Why'd I let you go?
                     Am   
I don't know how to say this
                        C
And you're not all that patient
                Em                D
Ever since you left, I've been alone
                      Am
I don't know how this happened
                  C
I got so distracted
                    Em
And now you're with someone
I know I was wrong
                      Am C Em D
Why'd I let you go?
                      Am C Em D
Why'd I let you go?
                      Am C Em D
Why'd I let you go?

[Interlude]
Why'd I let you go?
Let you go
Am C Em D (x2)

[Verse 3]
                    Am   
I don't know how to say this
                        C
And you're not all that patient
                Em                D
Ever since you left, I've been alone
                      Am
I don't know how this happened
              C
I got so distracted
                    Em
And now you're with someone
I know I was wrong
                       Am
You said that we were worth it
                     C
We could've been so perfect
               Em              D
Everything was easy, what went wrong?
                       Am
You said that we could have it
             C
But it never happened
                 Em                 D
Because I didn't see it, now you're gone
                      Am C Em D
Why'd I let you go?
                      Am C Em D
Why'd I let you go?
                      Am C Em D
Why'd I let you go?
