Pay Dirt is Slate’s new money advice column. Have a question? Send it to Athena and Elizabeth here. (It’s anonymous!) My partner grew up poor, while I grew up more middle-class. He has always controlled all our finances, and spends hours monthly on budgeting and checking bills, credit cards, etc. I’ve never known anybody who obsesses like this. All income, including gifts, goes to the joint account, and I have to keep receipts for everything I buy, down to a coffee, so he can record and check it. We have a fairly big (but manageable) mortgage, and our child has added many more costs to our lives, but otherwise we’re OK.
