Apart from the mention of the word "wife" there's nothing wrong with the ad. -only his ambition. Who'd be able to or even want to do all of that stuff? But that's another matter altogether.
But even his phrasing is a little ambiguous: "I’m not looking for strictly a professional housekeeper and neither am I looking for strictly a personal assistant…kind of a virtual wife." Is he really saying, I'm looking for a kind of virtual wife, or is he saying I'm NOT looking for a kind of virtual wife? The way it's phrased it could be the latter, in which case, we're all misreading his... needs.
