I see this question as an opening to chatter on at length about my husband, and his general awesomeness, so if you don't want to hear that, don't ask! Along with my wonderful children, he's one of my favourite topics of conversation.
Maybe that's why I rarely get asked this question any more.
Also, I'm not sure what's supposed to be so "personal" about a short answer that implies (or openly states) you were living together before marriage.
Most folks do, don't they? I don't personally know anyone who didn't...
