I'm always surprised when I hear about spouses who do not share the interest. It seems to me that one is attracted to people with similar tastes. I don't want to come off sounding judgemental, I mean I'm sure there are many good reasons you two are a duo. It's just that when I met my better half we were both involved in activities that we shared an enjoyment of, and we later grew to know each other's interests in such areas as sci-fi, costuming or whatever.
I guess in short what I'm saying is I don't really know what to say about this question.
