Everything you own in the box to the left

There's a Beyonce song in the charts right now "Irreplaceable".

The chorus goes like this

"You must not know about me
You must not know about me
I could have another you in a minute
matter fact he'll be here in a minute - baby

You must not know about me
You must not know about me
I can have another you by tomorrow
So don't you ever for a second get to thinking you're irreplaceable"

She's just got rid of a guy who apparently has been cheating on her, and she wants "another you" ?? Did I miss something ? Can't this strong independent woman survive without a man ?

No, give me Gloria Gaynor and
I will survive any day !
