I don't hide anything from my wife. I'd rake ALL my hunting gear into a pile and burn it before I would let it damage my marriage.
But she and I know that we each like different things, and that we each have weaknesses for spending too much money on those different things. We help each other NOT blow money on unnecessary things, but we often look the other way, too. I'm the boss, the king, but she's the queen, and we share the kingdom. She's the perfect help for me, and I wouldn't have it any other way.
