In France, you have 900 years of romantic love going back to the troubadours and minstrels that wrote stories of Lancelot and Guinevere. You have gallantry at the highest level.
How many times have I heard in France of women who have been married for many years and the husband has had mistresses and you ask, "Why does she put up with it?" Because she loves him! Love is justification for so many things Americans would never put up with.
