I'm fortunate in that we have lots of women in our gaming circles, and therefore if we get them, we are able to get the boyfriend too, or vice versa.
Indeed. Gamer couples are excellent for planning purposes because they show up as a unit; as a rule, if one can make it, so can the other. We've got one in our group and it makes planning for the seven of us considerably easier.
(That said, there is a big difference between a true gamer couple and a couple where one is a gamer and the other shows up to play because s/he wants to be involved in what the first one is doing.)
