Facebook privacy question?

[The Kellster]

I'm having trouble figuring this out. I want to change my relationship status (from nothing to single), but I want to keep my relationship status hidden from some of my facebook contacts (my coworkers) because it's none of their business!

When I click on "privacy" in the top right corner, and then click "profile" (where I'm supposed to be able to control who sees my information), there isn't a spot for hiding my relationship information. I'm confused, because the Profile Privacy groups don't match up with the way information is grouped when I go to edit my profile.

Help? How do I hide my relationship information from certain people?
