Cyrena said: "You say you've been "up-front" about your whole relationship with "anyone to whom it might matter." It's telling that the one person one might assume it mattered the most to--your wife--is the one with whom you've never been up-front."
I agree, and the other people who are affected by his choice to have affairs who he hasn't been upfront with are his children and his wife's relatives, all of whom I doubt would agree with any of his justifications.
