Of all the marriages, over half end in divorce. How many of the rest do you think are truly happy?
I think it's a rarity that a couple stays happy until one passes away.
It's important to keep in ming that 50% of PEOPLE don't get divorced, 50% of MARRIAGES end in divorce. People who marry many times skew the statistics. So for instance, my parents have been married for 35 years. They only get counted once. My husband's father, however, has been divorced 3 times, and his mother 4 times. So even though they are only 2 people, they have 7 divorces between them, and each of those divorces gets counted statistically.
The way you view marriage (that is, whether or not it is happy) I think largely depends on where you live, and the kinds of people you associate with. When I lived in the deep south, a lot of people I knew got married right out of high school. You're young at that point, you don't really know who you are. I saw many marriages break up, or not be happy ones. Also, there is much more social pressure for the woman to stay home with the kids, which leads to financial hardship, which also strains marriage. Also, being in an area with a poor job market and little value on education, where most people are poor unskilled workers, also of course adds to financial hardship, even when both people are working.
But here in Massachusetts, people WAIT to get married. People get married after they've finished college, then grad/law/med school, have gotten established in their career, etc. My husband and I were married at 24 and everyone thought it was so young, in fact we had a lot of friends and family members who really urged us to wait longer before we tied the knot. Also, it's a lot more rare for a woman to not work outside of them home (unless she's married to someone wealthy, or is an older woman). People are also more educated here, which leads to higher paying jobs. So that combined with having a two person income lessens financial strain. Massachusetts has the lowest divorce rate in the country. I know very few divorced people here. Most married people I know are fairly happy. And even the ones I have found who are miserable married, typically were people who were miserable alone as well. They're just miserable individuals in general.
Though I should add that we have a lot of old Catholics here in Massachusetts who just won't get divorced no matter what.
