OH MY GOD , WHERE ' S THE BATHROOM , I NEED TO POOP SOOOO BADLY . <| sep |> I used to do that , except on excel and it was for debits and credits from my bank account , not every single exchange of money for goods and services . So once I withdrew cash , for example , that was a single entry . Not every single thing I bought with the cash afterwards . I did it to track my spending during a period when I was struggling financially . But I can see someone getting obsessively anal about it . It can be really helpful . The actual tracking I don ' t think is that big of a deal if that ' s his method of financial responsibility . The bigger issue is viewing things as yoursmine . You guys aren ' t married or even engaged so it ' s not that huge of a deal yet , but will he ever be able to adopt a ' we ' mindset once you guys are a union ?
