A response to various ideas expressed here - I think we need to drag in GKC, but will address the thoughts of others first - don't you hate it when it seems no one responds to your thoughts at all and they keep talking as if you never said a word? In genuine (honest) debate that seeks to prove the truth, opponents listen carefully, with bated breath, to every word of their opponent, seeking weakness in their ideas. In modern political debate they simply do not listen to each other at all but merely harp on "talking points".
So, because I HAVE been reading what y'all have posted here...
"It lasts": The feeling of 'falling in love' does not last. Period. Ever.
A marriage, however, can last, even if you do not always enjoy his or her company. So saying that a marriage can't last because desired feelings have ended is not true. Feelings come and go, and they can even be created by how we are with the other person. It is very hard to hate someone who is consistently loving you, and very easy to experience positive feelings. Divorce cannot be justified merely because we have grown tired of the person we pledged our lives to.
Our society HAS based the idea of marriage as based on a feeling. What is NOT wrong with that idea is that the feeling of falling in love can and does serve as an excellent way of 'starting the car' like a battery does. It is a terrible generator, though, and trying to use the battery as a generator will fail in the end. IOW, everything else is wrong about the idea of a marriage based on feelings. (I'll avoid the evil euphemism "relationship" - something we should try to delete from our vocabulary due to its intensive use regarding marital relations without the marriage itself.) But focusing on a marriage 'arranged' by feelings vs one arranged by parents is going in the wrong direction. That is not the issue. However the marriage comes about, the issue is of the vow as a sacred thing that seals the marriage for life and creates a new family and new relations (called "in-laws" in English), once that are not negated by the mere superstition of divorce.
Saying "I believe" is rather dangerous. It is both good and true, but it also seems to reduce the idea to one's mere personal opinion, rather than an absolute truth binding on all regardless of how they feel about it.
Philothei brings up an excellent point. I would expand on it by saying that the problem of the modern insanity is based heavily on what Mr. Spock of Star Trek once called "two-dimensional thinking" (for those old enough to remember the reference). They only see what is NOW. They can barely see what was 15 years ago, and have been fed a nearly completely false view of history (with grains of truth to hold the false view in place). Comments like what colleagues may think of our heroine psychiatrist (I quite mean that) now are symptomatic of this. It is not asked what colleagues of a hundred years ago said - the idea occurs to no one. It is assumed that our ancestors of 50, 100, 200 or 500 years ago were benighted individuals who were inferior in both knowledge and wisdom. It is precisely for this reason that I find so much the modern "psych" sciences to be suspect. Amazingly, humanity got along for centuries, even after the Renaissance, without the benefit of those 'sciences' (and I do think there is real science in there). The fact that they arose in the aftermath of the so-called "Enlightenment" (read "Endarkenment"), which was about 'casting off the shackles of religion' speaks volumes. And later some, aided by Darwinian ideas that Darwin himself did not hold, decide that there IS no soul! And in that soup the "psych" sciences - sciences of the soul - were born, in a very atmosphere of science already rejecting God. The sould would henceforth be 'treated' without any reference to divine human origin - and if there be no soul, so much the better (from that perspective). We would learn to be our own gods.
