Romantic love begins as two peoples' mutually experienced, overpowering sexual desire for one another.
In order to justify giving in to that desire, it is typical for people to elevate their feelings to some sort of spiritual level, so they can avoid feeling shame or guilt over having sex which they have been taught throughout their lives is inherently sinful unless blessed by some sort of unquestioned authority.
This idea is primarily Western though (although it has influenced other cultures owing to the world-wide dominance of Western culture). In the rest of the world, arranged marriages are the norm, and from what I've seen they are generally more successful than Western "love matches" (I work in IT and many co-workers are in arranged marriages, so I have some knowledge of the subject).
Romantic love eventually leads to the sort of love felt between members of the same family. Over time, families (unless they are fundamentally dysfunctional) develop strong bonds that will cause members to defend other members to the death. Many families do fail because couples expect romantic love to continue and grow stronger, so they can't handle the disappointment of not experiencing that.
Ok my issues with this. Most of us don't feel shame around sex. Ok, I'm not American so haven't been subjected to puritanical culture. But going by my non-religious family. They weren't looking for great reasons to justify having sex, they were looking for love and connection and a partner to share their life with.
I'll bet divorce isn't allowed in those cultures you've pointed out.
Is it length of marriage or is it contentedness within the marriage more important? These long marriages could be rife with misery.
