Post-Romantic?

I was reading a blog the other day about a new book by Pamela Haag:  "Marriage Confidential: The Post-Romantic Age of Workhorse Wives, Royal Children, Undersexed Spouses, and Rebel Couples Who Are Rewriting the Rules.".  What a title!  Kind of takes the shine off the white gown and all.  Basically the blog and article http://marriageconfidential.com/ talk about us living in a post-romantic era in which the possibility of life-long monogamous marriages are becoming a thing of the past. The article cites a Pew study which discovered that 40% of Americans believe that marriage is becoming obsolete, and that Americans are in the process of redefining it.
Can we really redefine marriage? Haag's opinion is that marriage's strength is in its adaptability to changing circumstances. One changing circumstance she cites is longer lifespans and shorter attention spans. This combination, she insists, may spell the demise of the lifelong marriage bond that resulted in Golden Anniversaries and beyond. Perhaps in the post-romantic era, there will be one marriage for child-rearing (though even that doesn't seem to be working so well) and one  or more for later fulfillment in life. As far as she is concerned, marriage is likely to become more heterogeneous and customized towards particular couples.
The Bible insists that marriage was ordained by God as a relationship where "two become one" for life. Even though people have a hard time realizing this ideal, does it mean that God's plans for marriage are now obsolete? Why not ask kids who have had to live through a divorce?  Even adult children who experience a parental divorce later on feel the pain and awkwardness of life as it should not be.  That is because marriage is not just about the individuals involved, but about the whole network of relationships that surround the marriage.  Marriage is not just about the couple, but about the community.
If Haag has her way, when a marriage fails to go the distance, it's not a matter of the couple failing to hit the bullseye of a lifelong commitment, but of letting the arrow fall where it will and drawing a circle around it, claiming victory.  Again, ask the children of divorce if they think someone hit the bullseye.
Because people are people, we will fail in relationships, sometimes irrevocably.  When we do, we need all the compassion and understanding we can muster for each other, for there is always pain involved when something goes wrong. However, to treat it as right and good is the greatest tragedy of all, for it trivializes the pain for everyone involved, including the couple whose dreams have been broken.
The good news is there is healing from brokenness through Jesus Christ for all circumstances, but only for those who realize something is actually broken.  What do you think?
