If I read the article correctly, the biggest change in marriage were the expectations about it, and I can agree to that. For much of time, marriages were generally a kind of contract, that bound the two people together, and in most societies in effect were ownership of the wife by the husband, she went from being ‘owned’ by her family to being ‘owned’ by her husband. That changed in the late 19th century, as women achieved rights outside the marriage, like owning property and being able to enter into contracts, but marriage was still this contract that was supposed to be inviolate, in many places divorce was either illegal, or difficult to get. And the standard line about a successful marriage was to ‘put up with it’, whether it was for the kids or religious reasons or whatnot.
That started changing when divorce became easier, and then after women seriously started achieving some measure of equality outside the home, specifically with economically being able to support themselves. They no longer were being told by their parents and society her duty was to her husband and kids, no matter what, and as a result expectations have been changing, and this article I think is pretty spot on, that in marriage both men and women have high expectations on what they need and to be happy.
I disagree with the article, though, on somehow that marriages back in the day were happier for most people, I think back then that the happiness (or lack thereof) was hidden behind a lot of playing to the public. It was much like claims of moral superiority of prior generations, it wasn’t that they were more more moral (they weren’t, the mores of Victorian society were not what is claimed by many today, it was in Victorian society it was anything went, as long as it was hidden behind the veil of propriety), it was they hid the morally ‘shocking’, and it was much the same with marriage, I suspect marriages were probably not more happy for the most part, but rather than people were taught/they caught, that you don’t complain about things, that with marriage, it is expected you make it work, and if you aren’t happy, well, that is life. On the outside, all was smiles and whatnot, on the inside, all it takes is reading memoirs of people of that generation, read the diaries of married women, to realize how much was just window dressing, that there were a lot of miserable people in marriages who had no out.
I can believe that those who work at marriage and on fulfilling one another do have happier marriages, part of that is when you work towards being happy, you also learn the art of compromise and realizing that what makes you happy isn’t entirely what works for another, and that give and take makes a big deal, among other thing, it shows respect to the other person. On the other hand, I suspect the marriages beneath this level suffer from the same problem they always did, that while the people aren’t happy, or as happy as they would wish to be, they still ‘gut it out’ rather than work on it. The most miserable get divorced, but in that mid range, you have varying levels of happiness and satisfaction along with a lot of ‘I only could wish’.Like I said before, I doubt that people in this mid range are less happy than people in prior generations, I think that it is in prior generations they were programmed to put happiness ad such as being ‘selfish’ feelings, and that their duty was to put up with what they have, whereas people today expect to be happy, but in that middle don’t know how to work towards it.
It may seem like this has nothing to do with issues with inlaws, but it does, because in both cases in deals with how to get others to treat you as you want to be treated, setting boundaries and compromising, and bad in laws are like bad spouses, they generally don’t want to compromise and don’t understand that someone else’s needs and wants in the relationship matter, so you end up with one side dominating and another angry and resentful, I also would bet that with bad inlaws, if you looked at their own relationship, it probably would be a mirror of that within the marriage.
