We solved this issue for the most part by having partially joined accounts. We have 1 joint credit card, 1 personal credit card, 1 joint checking+savings, and 1 personal checking/savings. 80% of each of our paychecks goes into the shared bank account. Then we each have our own set of bank accounts that the other 20% goes into (+ whatever money we had before we were together). We pay bills + shared expenses (things for the house, medical expenses, etc) out of the shared account. Personal expenses are paid for out of our individual account. This means we don't have fewer about the other person buying things. In other words, I don't care if he spends $100 a week on drinks after work, or has a latte addiction, or only wears italian leather shoes, because their his things paid for by his money. (Note, he doesn't actually do any of those things, lol). There are some keys to making this work -- 1. Decide on a percentage you both contribute, not a dollar amount. We calculated our (very general) budget of rent + expenses + savings, and then determined a $ amount that we had to have each month, and just made sure that X% of both our incomes hit that amount. 80% ended up being more than enough, but we don't have that many personal expenses anyway, so we decided not to make it lower. The key to having percentages is that it's fair even if you're making different incomes, so one person doesn't feel like they're spending "all their money" on joint expenses. 2. Direct deposit. We had the issue where my FI didn't set up direct deposit for several months when he started a new job, and kept forgetting to deposit his checks. I kept having to take money out of savings and freaking out, and eventually he transfered like 6 months of back-pay in all at once, so our finances were all over the place. 3. Clear boundaries on what's personal and what's not. Some things are obvious. If I'm going out to lunch with coworkers (obviously without him), its my expense. Clothes, salon visits, all personal. If he's buying games to play on his computer, it's obviously his expense. There were somethings we had to decide as they came up. For instance, we decided after the fact that medical expenses would be shared. I ended up getting really sick a couple months after, so it was good that we had decided on that before the medical bills started piling up. We still struggle with this sometimes, but for the most part it's a good system. Yes, sometimes there's a grey area. For instance, we both play video games. If he buys a 1-player game, but I want to play it too, is it personal, or joint? I started taking classes at the local CC, and I paid for them personally (since he's not in the class), but he said that could have been a joint expense, and he wouldn't have cared. The most frequent thing is that I can never finish a meal at a restaurant (seriously, those portions sizes are way too big), and I always pay for them personally, but he sometimes eats my leftovers. I don't want to say "I paid for that myself, so you now owe me $4 for that half of burrito". For the most part, I don't sweat the small things, because we buy each other meals / gifts all the time, and at the end of the day, it's not a big deal. We adapted this system from what we read in personal finance books. My two favorites (but very different books) are "Smart Couples Finish Rich" and "Young, Fabulous, and BROKE"
