Dalrock recently put up another thought provoking post. He gives a commentary on a truly awful film, Fireproof. The film is about the breakdown of a marriage and its story is typical of many marriages. You can go over to his site and read about the details of the movie and his commentary, but I thought it would be worthwhile to make a few comments of my own, especially on the subject of love.
A while ago I wrote a post on the subject of "parasitic lovers". It appears to me that a lot of marriages today are an arrangement of mutual benefit between two parasites ; each staying in a relationship only as long as they are a recipient of some benefit from the host. As soon as the host stops providing the benefit they move on. Another name which I've seen to describe the phenomenon is "Hedonic Marriage".
"Hedonic Marriage " really should be seen as a "fruit" of the modern culture and it is the end consequence of viewing marriage as a sort of "contract"; an exchange of goods. I suppose it is the natural consequence of the "Me" society; a view which places the happiness of the individual above else, even above the happiness of those about them. It's inevitable that in such a culture its constituents will want to emphasise their rights whilst dismissing their obligations. It is the underlying motive behind social atomisation.
Symbiotic love, on the other hand, recognises that's its own well being is contingent upon the well being of the host. Even at its basest level, the recipient of the host's benefits recognises that if they wish to continue receiving them, they've got to ensure the well being of the host. Unlike parasitic love, it is the love that binds.
