<prompt> Human: This is a general question, I dont have any serious money problems, and I do monitor my spending meticulously. However, I am frustrated by the fact that I have been spending more, despite the split rent utilities etc. I know which areas I have been spending more on, I just expected otherwise - or is this actually typical?  <response>: I think this is common but depends somewhat on your partners spending style. I noticed definite differences when I moved in with my partner. For example, my clothing costs went down a bit most months he hates shopping, so now I do less clothing shopping as entertainment compared to before but my entertainment costs movies, concerts, trips to the city went up because thats where he likes to spend money and I like to go with him.Sadly, I think unless youre watching it, costs tend to increase to approximate the less frugal partners spending in each category. He now does more clothing shopping than he used to, for example! :Note: We have a similar spending system to ThisIsMyUsual... Individual expenses are individual, and we each buy our own ticket at the movies most of the time. Shared expenses like groceries, rent, utilities, and household items get added to a spreadsheet and squared up every two months.
