Love is a symbol of eternity.

Love is a symbol of eternity.  It wipes out all sense of time, destroying all memory of a beginning and all fear of an end.

It's true that in many cultures, people who are "in love" create long-term partnerships and/or get married. We may hear of the high divorce rates, but lots of these couples do actually stay together. Yes, there are couples that have been married for 60 years and still feel passionately in love, and there are others who care deeply for one another even though the lust is gone (or maybe never existed!). Of course, sometimes we may not even want to hear about the happy, lovey-dovey couples because we're feeling romantically unlucky or lovelorn ourselves.
