"Understanding" lyrics

I'm way past my limit
Somebody better grab my phone
Somebody better grab my phone
'Cause I've been callin' you all day long
Who's got you waitin' over text messages
When you were at my crib
Just a week ago
Or was it just a week ago?
I wouldn't know but

If you saw somebody lurkin'
It was me
If your window bust open
It was me
It wasn't your baby mama
It was me
Sorry, it wasn't a robber
It was me
Calls from a blocked number
It was me
Key marks on your Hummer
It was me
If you got a flat tire
It was me
If your clothes on fire

You are not my man but I better not catch you cheatin' on me
Boy, boy
We are not together but we got an understanding
Don't we boy, boy?

We got a situation, situationship
Don't make it complicated
Don't go wastin' all my time
Don't you throw off my vibe
'Cause if we get it right, might turn my X's into Y for you

Pull up and run it
Tell me I'm your one and only
Pull up and touch it
Boy don't leave me lonely

If you saw somebody lurkin'
It was me
If your window bust open
It was me
It wasn't your baby mama
It was me
Sorry, it wasn't a robber
It was me
Calls from a blocked number
It was me
Key marks on your Hummer
It was me
If you got a flat tire
It was me
If your clothes on fire

You are not my man but I better not catch you cheatin' on me
Boy, boy
We are not together but we got an understanding
Don't we boy, boy?

Tell me that it's mine, all mine, all mine
I know that you ain't mine, all mine, all mine
Tell me that it's mine, all mine, all mine
Yeah
Tell me that it's mine, all mine, all mine
I know that you ain't mine, all mine, all mine
But tell me that it's mine, all mine, all mine
Yeah
Baby, I'm crazy

You are not my man but I better not catch you cheatin' on me
Boy, boy
We are not together but we got an understanding
Don't we boy, boy?
