Same here… my GF regards it as potentially intrusive for her to join up (and she would not appreciate it if I joined some of the boards she participates in… it would curtail her freedom to tell tales on me! 
)…
but she does ask me to post a question to the Dope on occasion, most recently about a noisy bird we were hearing outside our window.
No spouse. I have enticed a few friends to post here, however.
My spouse posted under my name one time. I don’t think that counts.
I chose “other” because my first husband was FunLvnCriminal, who hasn’t posted here for a number of years but was the “Ask the guy who had weight loss surgery” guy. So, ex-spouse posted here, but I got custody of the SDMB when we divorced. Also, I have sometimes had a sneaking suspicion that my boyfriend posts here sometimes, but I haven’t asked him. I figure we’ll let some things be mysterious for a while. 
My husband made an account when I first started posting here, but I don’t think he has ever used it. I doubt if he even remembers he has it.
My SO has lurked on occasion. Mostly he just says to me “those Dope people of yours.”
I put “spouse posts here” but he’s only posted two or three times ever, so it’s really just a technicality. I did not meet him on the SDMB.
My spouse and I met IRL. She forums elsewhere. The dope is not her cup of tea.
My wife doesn’t consider people I only know online (Dopers, my WoW guild) to be “real” people. I don’t know if she thinks you’re all computer simulations, or fat Asian hackers, or what.
My wife has met a bunch of you and considers you all too real. Collectively, you are “the mistress I spend too much time with.”
My husband doesn’t post here but enjoys tales of your collective wisdom and foibles very much.
Spouse posts here on occasion. We met in a parking lot many years ago while engaged in geek activities (no chickens were harmed). We started reading SD in a local alternative newspaper early in our married days and lurked online for years before joining, so while the SD did not bring us together, it was one of the ways we strengthened our marriage bonds in the early years.
Spouse doesn’t post, doesn’t lurk, and can’t remember the name of this place.
I don’t have a spouse, but my friends always have a chuckle whenever I we have a question that I “ask the internet” about.
She also says “I love it when you talk about your internet friends”.
Pepper Mill never felt the need to follow closely, although she does love some of the stuff this Board brings up. And she contributed to one of the early issues of Teemings

MilliCal, our daughter, on the other hand, peruses the SDMB, and I suspect she may end up posting.
This. Although mine has expressed interest in attending an OrlanDope, if we get around to having another one.
Mrs Magill doesn’t post here, though she knows people who do. She’s expressed an interest in coming to a minifest some time.
My fiancée has posted here. Once.
I’m a computer simulation of a fat Asian hacker.
I voted for “other.” My former spouse used to post here, and, in fact, introduced me to the board. My current girlfriend is someone I was fortunate enough to meet via the Dope.
Love is, after all, often about fighting ignorance.
