Putting the shoe on the other foot, imagine what it would be like having your wife track your spending. Not necessarily a bad thing, but ideally it should be something that, if necessary, works for both of you.
As Morrison says, it ultimately comes down to sharing the same mindset or at least having mindsets that don't conflict. In my own limited experience, this seems critical to any hope of retiring early and comes before any discussion of investment strategies etc.
That said, if you can earn enough to support a free-spending spouse (and some people do), more strength to you.
