[Verse 1]
I'm leaving if you say so
But I will never let you go
Gets harder when the lights go out
I wonder how your day goes
Or if you'll ever feel at home
'Cause I don't ever feel that now

[Pre-Chorus]
I miss the world when you were mine
I miss the hi's and the goodbyes
'Cause I just thought you were coming back
So why you go and do me like that?

[Chorus]
How can I leave you in the past
When you're the best I ever had?
If you don't want me back
I'll go, but I won't
Leave you in the past

[Drop]
Leave you in the past
Leave you in the past
Leave you in the past
[Verse 2]
It's hard for me to cut ties
When my memory keeps you alive
I don't know when you're hot or cold
But I'm still holding on tight (Holding on tight)

[Pre-Chorus]
I miss the world when you were mine
I miss the hi's and the goodbyes
'Cause I just thought you were coming back
So why you go and do me like that?

[Chorus]
How can I leave you in the past
When you're the best I ever had?
Got to live with that
I know
How can I leave you in the past
When you're the best I ever had?
If you don't want me back
I'll go, but I won't
Leave you in the past

[Drop]
Leave you in the past
Leave you in the past
Leave you in the past
[Pre-Chorus]
I miss the world when you were mine
I miss the hi's and the goodbyes
'Cause I just thought you were coming back
So why you go and do me like that?

[Chorus]
How can I leave you in the past
When you're the best I ever had?
If you don't want me back
I'll go, but I won't
Leave you in the past
