[Verse 1]
Let me explain it, when I did you wrong
I didn't know I'd feel this regret
But it drives me crazy to see you move on
While I lay alone in my bed

[Pre-Chorus]
If I could rewind, take a step back in time
I would never do you like that
I made a mistake, so now it's too late
And there ain't no way I'm gettin' you back
You got me sayin'

[Chorus]
Damn, I shouldn't have let you walk right out my life (Uh)
I shoulda treated you right
I shoulda been by your side
Like damn, I slipped and let you catch somebody's eye
And now I can't even lie
It's killin' me inside
Like damn, I shouldn't have let you walk right out my life
I shoulda treated you right
I shoulda been by your side
Like damn, I slipped and let you catch somebody's eye
And now I can't even lie
It's killin' me inside

[Verse 2]
Can't get no closure, but we said goodbye
I still feel the same as before (Before)
Keep my composure, believe me, I've tried
To accept you're not mine anymore (No)

[Pre-Chorus]
If I could rewind, take a step back in time
I would never do you like that, baby
I made a mistake, so now it's too late
And there ain't no way I'm gettin' you back
You got me sayin'

[Chorus]
Damn, I shouldn't have let you walk right out my life (Uh)
I shoulda treated you right
I shoulda been by your side
Like damn, I slipped and let you catch somebody's eye
And now I can't even lie
It's killin' me inside
Like damn, I shouldn't have let you walk right out my life (Walk right out my life)
I shoulda treated you right (Ooh)
I shoulda been by your side (By your side)
Like damn, I slipped and let you catch somebody's eye (Catch somebody's eye)
And now I can't even lie (Lie)
It's killin' me inside

[Bridge]
Damn, I shoulda never let you walk out my life
It's killin' me, it's killin' me inside
Damn, I shoulda never let you walk out my life
It's killin' me, it's killin' me inside
Damn, I shoulda never let you walk out my life
It's killin' me, killin' me inside
Damn, I shoulda never let you walk out my life
It's killin' me inside (Woah)

[Chorus]
Damn, I shouldn't have let you walk right out my life (My life)
I shoulda treated you right (You right)
I shoulda been by your side
Like damn, I slipped and let you catch somebody's eye (Eye)
And now I can't even lie
It's killin' me inside
Like damn, I shouldn't have let you walk right out my life
I shoulda treated you right
I shoulda been by your side
Like damn, I slipped and let you catch somebody's eye
And now I can't even lie
It's killin' me inside

[Outro]
Damn
