I believe you, as I have no reason not to. I forget to tell my wife stuff all of the time, but there is no way that my giving money to another woman would have slipped my mind! I bought and installed a car battery for an unmarried lady just last week, took my 18 y.o. daughter with me, and told my wife beforehand. That way, she never has reason to doubt, or be surprised by "revelations".
You’re also not a millionaire.
