One of the big assumptions of our times is that if love is real, it must by definition prove to be eternal. We equate genuine relationships with life-long relationships. We appear fundamentally unable to trust that a relationship could be at once sincere, meaningful and important – and yet at the same time fairly and guiltlessly limited in its duration.
A great many of the pleasures and virtues of relationships do only reveal themselves over time, once trust has been established and loyalty fully demonstrated. Not least, children always benefit.
