Say what you will, making marriage work is a woman's business. The institution was invented to do her homage; it was contrived for her protection. Unless she accepts it as such --as a beautiful, bountiful, but quite unequal association --the going will be hard indeed.
The institution of marriage in all societies is a pattern within which the strains put by civilization on males and females alike must be resolved, a pattern within which men must learn, in return for a variety of elaborate rewards, new forms in which sexual spontaneity is still possible, and women must learn to discipline their receptivity to a thousand other considerations.
For it is mutual trust, even more than mutual interest that holds human associations together. Our friends seldom profit us but they make us feel safe. Marriage is a scheme to accomplish exactly that same end.
After seven years of marriage, I'm sure of two things -- first, never wallpaper together, and second, you'll need two bathrooms.. both for her. The rest is a mystery, but a mystery I love to be involved in.
