At what age do you think kids start to figure it out for themselves if they have parents in an open relationship?
I have always been a "live and let live" type of person. Whatever works for you, go for it. But I do think that gets murky when you talk about kids being in the picture -- at least to me. They will begin to figure it out. Perhaps honest dialogue about it makes it all ok for some. Wouldn't be on the table for me, personally.
Honestly, I knew people in open relationships when I was in my 20's. Not these days. No idea if that's because fewer people do this sort of thing as they get older, or because I'm running with a different crowd these days... ...
