[MENTION=46029]fender1[/MENTION] is right to an extent. I don't hide significant purchases from my wife. That would be a form of lying about an important resource and therefore a breach of trust. Our money is arranged as yours, mine, and ours, but even blatant waste of my own money would be significant even if it isn't a direct problem. My wife sees stuff come and go, and she knows that I pay for some and I get money for some stuff I sell. I think it goes without saying that I'm not breaking even overall, and there's nothing wrong with a hobby that costs money.
