<prompt> Human: My fiancée and I want to find a reliable system for managing our income, savings, and expenses, also without introducing stressarguments. We are both 30 yrs old, employed, manageable debt, no kids, no house. We generally agree on lifestyle needs, but have not been reviewing each others spending. Any good advice on what resources to pool or not? E.g., combine everything? Or separate accounts but divide living expenses? Only discuss major purchases? Or any systems that do not work or have caused problems for you? Thanks in advance!  <response>: It really depends on the couple. The more you are alike with finances, the easier it will be. Note that it may take some time to understand each others financial habits and get in the groove of sharing responsibilities and determining who is responsible for what.Everything is pooled together for us we do have separate credit cards and retirement. My husband could be more interested in finances, but that is about my only minor complaint. He makes a little more than twice as much as me, and I handle all the bills and investing which I dont mind at all and actually enjoy. He is not good at keeping up with bills, so it works out well for us. I keep him updated on our accounts, and what large bills will be coming up. I also have an account with mint.com and have all text alerts go to his phone - he doesnt have a desk job, thus no access to a computer so this is what keeps him updated.We both freely spend money without getting on each others case, but thats because we trust each other and know the other person will never go overboard. We always discuss before any large purchases 100.
