I read a study that showed the majority of successful, happy, long-term marriages have a fair amount of distance and independent time away from each other. That fact completely discredits many of the Romeo and Juliet fantasy stories. One soul-mate for everyone, a perfect person for everyone, is, IMHO, a myth and a fairy tale.
On the other hand, a loving spouse that is a good friend is not only indispensable in child-rearing years, but even more important in senior years. Children can fill some of the gaps for social, entertainment and care, but a senior citizen can become a burden on children who are already pressed for time to raise their own children, care for their own spouses and put in a lot of hours working. Every activity is more fun when it is shared, and seniors have time for those activities.
Seniors with spouses are healthier and happier, too.
Romeo and Juliet were only 14. They just wanted to get their freak on. Shakespeare just flowered it up a lot. Romeo just wanted to "de-flower".

Get that adrenaline going and the hormones sparked up and people will risk their lives just to be together.
