Well, you must be Jake's hot date. I'm Melanie, Jake's snotty Yankee bitch wife whom he refuses to divorce.

Our reading
An editorial interpretation.
The speaker greets an apparent date by introducing herself as Jake's wife and adding that he refuses a divorce. The formal introduction becomes a barbed disclosure of marital complications. Her deliberately insulting self-description makes the greeting sound confrontational while keeping its surface shape of polite acquaintance.
