Verse 1
You know this isn't right
Calling me at night
While she's lying In your bed
Your phone is by your side
You better change your mind
I won't be picking up again

Bridge
Why you looking at me to be the next one
When you’re not even done with the last one
What you’ve done to her
I just don’t deserve.

Chorus
I'll make this easy for you
You shouldn't be confused
You never had me to lose
So you don't have to choose
Does she know you're single?
Does she know you're single?
Does your girlfriend know you're single?

Verse 2
Shes waiting in the car
While you're in the bar
Spilling lines like Casanova

I want my Romeo
No lethario
So your winning streak is over

Bridge
Why you looking at me to be the next one
When you're not even done with the last one
What you've done to her
I just don't deserve.

Chorus

Middle 8
So next time I’m on your mind
Don’t you start to walk that line

Chorus

Does she know
Does she know
Does she know you’re single?
