We haven't yet decided whether we'll be 'out' or not. If we do decide to be out our families will not be told, in fact only a small circle of our friends will know. I am not intending to let work colleagues know, even if I am close to them.
I'm a very private person anyway, but I view my personal life as just that - personal. However much I'd love to be able to be open with everyone the risks of being judged, gossiped about etc. are too high for me to tell everyone. Plus professionally, being open about polyamory could affect my career. I work in education and professional boundaries have to be very clear.
