Want to pose a question

Well i didnt tell her, i just went and opened one to keep track of bills and gas in my car to make things a bit easier on my accounting. But she is pissed off at me. Says it was underhanded and sneaky even though that was not my intent, it was to make something in my life easier by only having to keep up with the bills and gas in my car which is typically all i use an account for anyways. My wife debits for everything, and then i have to try to account for it all on a weekly basis, and figure out whats in the account. Then we get into spats over who spent what and where. I figured by doing this it would eliminate that issue.
Just give her access to check it. If you are not worried about her taking out money, then she can check it, and will get over the miscreation. They don't really bring it up until another fight occurs about finances. I would tell her she has access to check it, apologies for creating doubt or mistrust, and that it wasn't your intention to go behind her back, just to track some of your expenditures. -best wishes brother
