We'll, we had a talk, and I set some rules. After 15 years of knowing each other and 12 years of marriage, I didn't think it would come to this.
She is not permitted to write checks for anything but immediate bills, for clothing or groceries. I will be getting a separate checking account for my income. If she needs money for anything that she can't cover (she works 3 days a week as a PT), she'll need to come to me first. She is in no way permitted to give to charaties or to invite men in the house to discuss fund raising (man, that rubs me wrong).
$600 to me is a lot of money, no matter what ones income is. My Denon 3805 blew up in November, so I shipped it to get fixed in Indiana. The repair took 2 months and $130. When shipping it back, UPS dropped it and sent me an insurance check for $785 (very lucky to have it insured). To date, I still have not purchased an AVR as these purchases take some time (not to mention I'm waiting for HDMI 1.3). For me to OK a $600 fund raising check to my kids day care school would have been an immediate "no."
I may have considered $50, but would have liked to know about it first.
