'Families and marriages fail too often because they are trying to answer too many human needs. A spouse is required to be a lover, a friend, a mother, a father, a soulmate, a co-worker, and so on. Few people can be all these things for one person. And when demands are set too high, disappointment can only follow. If husbands and wives have deeper and stronger friendships outside the marital unit, the marriage has more space to breathe and fewer burdens to bear.'
Andrew Sullivan, Love Undetectable, p.234.
