Both DH and I work very hard and we share everything that we have so it's never like his money or my money. If we buy something for me, it's always from him, and if we buy something for him, it's always from me. It makes us appreciate the "gift" more so anyway, about the telling or hiding part, I think it's more about respect than anything else. True, I don't have to tell him what I buy, especially when I know I went overboard, but I think he would get mad for not telling him, just like if he went overboard on his cars and parts spending and if he didn't tell me ahead of time, I would get mad. So we generally try our best to tell each other what we are buying. But I know it's hard sometimes, I am now hiding a Chanel wallet from him because I had just bought a purse and a woc during the past two months so it was more of my self consicious not to disclose the wallet until a later time. It's somewhere hidden in the closet and I don't plan on using it until couple things later.
