That’s pretty much what we did. My wife is the disciplined, organized one so I put her in charge of the finances. My job is to code the spreadsheets and make the money.
Sounds to me like you two are the perfect couple!! I am the type of person that thinks we all have our strengths and weaknesses. I think the “smarter” people in the world are the ones who figure out what they aren’t good at and assign/give over that type of job to the other spouse. In the case that I discussed, there isn’t any sort of secrecy or anything negative. It is simply a job that one did better.
I started out as the one who was pushing getting spending under control (Cummuta’s materials before Ramsey was around, then “America’s Cheapest Family, then Ramsey), but once my wife really got into it, she’s been a beast. 3-ring notebook, pencil, categories, you name it. We’re well on the way, down to just the mortgage and one (interest free, thank you, MOAA) student loan.
Married couples HAVE to work together on financial discipline, it just doesn’t work any other way.
