<prompt> Human: My wife is going to grad school and will have student loans, we may apply for a mortgage in the next 6 months, etc. Assistant: Only disadvantage Ive seen is if you have a hobby that she doesnt like, she can see every purchase for that hobby and bring it up. A coworker of mine is in this predicament, he likes buying fountain pens and ink he can afford to, his wife thinks its a waste and he should just buy cheap pens. Otherwise, shouldnt be an issue as long as youre both on similar financial wavelengths.Human: thank you for this. was still hoping to hear some disadvantages. i am not addicted to fountain pens and the weed store here in WA state only accepts cash so my habits are light haha. Thank you!  <response>: Though I think the simple solution is basically to agree on personal budgets. My husband and I each know approximately how much we can spend on our own things e.g. hobbies, gifts for the other person, shopping sprees, etc. that the other cant say boo about. It also helps that we both have our own credit cards, with separate statements. So if he wants to buy a gift for me, or generally have some modicum of privacy financially, I dont see the itemized breakdown of how he chooses to spend his money, and vice versa. We both see the statements paid out of the joint account and trust the other isnt running up a huge debt and so if one persons seems crazy high, they might ask the other why e.g. I bought plane tickets the other week so my statement is going to be like 800 more than usual but otherwise were free to spend our money how we wish.
