Admitting to your anger, love, trust, and vulnerability is an essential element to bonding lovers and friends alike. A sense of humor about each other and especially ourselves. Anything that you can't laugh at part of the time has you beaten. You've lost your perspective. Dedication to happiness as opposed to pleasure.
Pleasure is right now.
Happiness is gained only by the ability to delay certain pleasures in order to experience other, better ones. Not that all pleasures must be delayed. But you have to discipline and discriminate in order to keep your life, and loves, in harmony. And I believe that even if agreement of ethical principles could be reached, each person ideally needs to decide individually how such principles would be applied in each case. I really could go on and on with these, but I think you might be better able to put something together for yourself.
