Richard and I have always found it slightly odd trying to count how long we've been going out. We used to basically use two dates to work from: the date when we started seeing each other and the date when we started seeing *just* each other (or rather when we first actually spent time together after deciding that). We're coming up to the latter of those now, and it's 5 years ago this year. But I'm going to have to start thinking about it differently I guess since we're *not* seeing just each other any more. In some ways that seems really sad. In others this anniversary still means more to me than the other. I guess in the awful terminology of polyamory it's when we first became primaries, but I don't want to think about it like that really.
