One funny detail from my past is that I was a subscriber to the "free love" philosophy back in the 60's. Even when people are honest and open about fooling around, the consequences are often bad. Jealousy is a strong emotion, no matter what you think about it. One of the reasons that friendships between men and women are so hard to maintain is this subtext thing.

Marriage where partners really trust and support each other is a rarity and a gift. Good luck to you all (I mean that kindly).
