Re: Wife joining husband in aikido class?
Met my girlfriend at aikido, we're getting married in a year or so. I'm her aikido instructor, off the mat she's my girlfriend, on it she's my student and we are very sensible about separating the two.
I've had people train with me who were a couple and I've never seen a problem with it. If it does happen then I'd say you're just as likely to find single people who make the environment awkward as married people.
