I've been married once, been with the person for 25 years, now divorced. For us the big question was, were we going to move to another part of the country together and live together. The marriage part was more of a secondary consideration and happened later. In both cases we discussed it, rather than it being some kind of surprise. So I guess I would say, while I am up for bringing up the subject, I am traditional enough that if there is a marriage proposal involved, the guy does it (and hopefully it is not a complete surprise at that point!).
