[on his book 'You Can Be Right or You Can Be Married] I set out to vicariously to live through the tragedies of others, hoping to glean some wisdom from the wreckage and to ultimately become so fluent in such failure that I would be able to avoid in my own love life.
I think the idea of positive conflict, and how to fight fairly, is the key to a good relationship. Don't surrender. Don't pick fights but don't avoid them. Admit if something bothers you.
It's a silly promise to say, 'I will love you forever'. No one can say that. it's just not true. I don't care. No one can say it and no one should be loved unconditionally.
