Kind of a big deal, when we started sharing the same last name we started sharing our cash. Sure makes it easier to pay the bills, and there hasn't been a problem with it so far (partially since we're decided that the bill-paying is up to just me so that there's no conflict on who's job it is to do what, and we spend pretty much all our free time together so that we don't buy stuff that the other doesn't know about, anyhow. Not that we care that much.) Only good if you're SURE that you know what you're getting into, could be bad if you're not with someone you can trust.
