Wait, you said western world then skipped to the 19th century. Did you want to discuss how Native Americans would marry to strengthen their family and it would bring shame and dishonor, even sometimes death on a man or woman to cheat or divorce from a spouse.
Western world and 19th century are not mutually exclusive. I'm speaking of the legal aspects, and in almost all of the US (Louisiana being the exception), that is the tradition of English Common Law. However, even in the Code Civil, marriage is still a property arrangement. I'm afraid that there is no current legal system outside of tribal territories that is based on Native American tradition, so it really isn't germaine to what a "traditional" marriage is, in legal history terms.
Or what about the fact that in the 18th and 19th century, a wife was EXPECTED to clean, cook and take care of the kids in THEIR home while the husband was providing the resources for the family.
Um, not necessarily. That depended very largely upon socio-economic class. In that era, domestic service was much more common; if you could afford help you hired it, because all of that cooking, cleaning, etc. was backbreaking manual labor, and a "good" provider would want to show that he had the resources to relieve his wife of that labor.
They didn't live two separate lives and occasionally hung out on the weekends because they had to work together to raise a family. Do you really think love wasn't involved in any of this?
Well, there is love, and there is contractual duty -- the consideration that I spoke of earlier. Believe me, people stay married for a long, long time for a whole lot of reasons that are not necessarily about love, though as a general rule, fondness will often develop over time when you live with someone. Fondness is a lot more normal than passion, however.
I'm a first-generation American, and just about every marriage that I am familiar with in my extended family prior to my generation was NOT a case of getting married because they loved one another -- and this in a country where divorce was not legalized until 1997!
My parents were fond of one another in their way, and they were married for 35 years (until my father's death). They also fought like cats and dogs every day of their married lives. They got married because my father wanted a good homemaker, and my mother wanted security and an escape from the second-class citizenship of 1930's spinsterhood. They were both very religious, and they took promises made before God very seriously -- they said until death do us part, and as far as they were concerned, that was non-negotiable. My paternal grandfather abandoned my grandmother with 8 children to raise, yet they remained married for another 30 years, and neither one ever said a bad word against the other in one of their childrens' hearing.
The traditions i'm talking about are the basic ones that have survived the evolution of marriage like loyalty, honesty, love and being faithful. Are you seriously telling me that you can sacrifice one of those and have a great marriage? Or living in two separate homes because you can't stand living with your spouse but want to occasionally hang out to prevent divorce, that's a healthy marriage?
But many of those "traditions" are quite new, in legal terms. Adultery on the part of the husband wasn't legal grounds for divorce in Common Law until 1857, and there was a huge debate on the topic, because many lawmakers feared that husbands would use that as license to escape from an unwanted marriage. (In the days before reliable records, once a man was gone, he was gone; there really wasn't any way to trace someone who was not wealthy or prominant, so if he didn't want to pay any support, it was a simple matter not to.)
As to loyalty, it isn't necessarily equivalent to love. How many people are loyal to an employer because of a paycheck? Or loyal to a political party because of what positions it does NOT support? You don't have to love someone to feel that you owe that person loyalty.
And no, popular culture defines marriage as Kim Kardashian or Jessica Simpson or Brittany Spears or anyone else that does it as a PR move or a relationship out of lust. And now they add another chic lifestyle by making it ok to live in separate homes if things get too rough. That's popular culture's version of marriage and that's what I've been talking to in my posts.
You can personally define marriage any way that you want, but one look at the wedding industry will show you that real popular culture (not just prurient celebrity gossip) defines marriage as being all about romantic love. To hear young brides (and Nicholas Sparks novels) tell it, it is supposed to be hearts and flowers for ever and ever. There is a huge reason that the Catholic Church requires counseling before a wedding will be performed -- in a faith that does not condone divorce, they want to be sure that you are going in with open eyes, not rose-coloured glasses. (It doesn't always work, of course, but they do try.)
Happiness and contentment in marriage is all about expectations. If both partners are completely open about their expectations and get those expectations continually met, it will be a good marriage for them. If you asked my mother if her marriage was happy, she would have told you that it was, because she got what she wanted from it.
