No.
I respect my wife enough not to lie about stupid crap. If I wouldn't tell her about it, I shouldn't spend it. She gets an informed vote in the family finances ... but not the only vote. She's my wife, not my mother. I don't take orders, and neither does she.
She respects me enough to know that I don't need her permission. She also trusts me enough to know that I'll do without if there are more important things, and I won't spend what we can't afford.
