My wife does our company books and I buy all my gear through the company, so there is no hiding anything. I never do anyway. I don't understand why you would not be honest with expenditures with the wife. Yes, I sometimes get some grief about purchases, but then so does she. Just keeping each other in check somewhat.
Besides, I am owed, I have bought $3.5k worth of camera gear in the last few months, she is at $12.5k in furniture. What the hell do you need expensive furniture for, and where the hell have my cable reel end tables gone anyway.
