I admit you look alright, sorta Low T, but decent. This is me: https://imgur.com/gallery/cuRVw. I'd give you a better pic but I currently don't have a phone, so I have to choose from a brief array of laptop photos.
Yeah, some people can make it work. The majority don't. Here is a chart of the divorce rate by country: https://en.wikipedia.org/wiki/Divorce_demography#Divorce_statistics_by_country. Again, America is roughly around 50%, and that isn't even near the highest total. That in and of itself is incredibly sad. But if 50% of marriages end in divorce, how many more trudge along unhappily? Probably a good amount. You'll also notice that third-world and Islamic countries have much lower divorce rates, probably because they are too strict or too based to dive into reckless hedonism. And you're right, probably very few people will notice. And that's probably because they've never thought deeply about the current state of affairs. Although I think some remnants of Feminism are starting to catch on, and some females are refusing to "give it up" unless a full commitment is made to them. Good for them, they are protecting themselves.
See, I see what you're saying about trial and error, and how no one's perfect. I absolutely agree that no one is perfect. So then why sift in and out of relationships searching for the "perfect" partner? Such a person doesn't exist. Sure, you can go on dates. But don't make a full-blown physical and emotional commitment to someone that may just end up "dumping" you, or someone you may end up "dumping". Imagine if two people met at, let's say, age 17. They loved each other and stuck it out with each other. Sure, they hit some bumps in the road, but they were always there for each other, and they cherished one another. Imagine how great that love would become! Contrast that to what you have now, which is people "dating", fucking, and "LTRing" loads of people before marriage. Once a person is past peak fertility, emotionally worn down, and has experienced everything with other people, they "settle" for partner #13 or whatever ("Settling" is literally what our society calls it, actually think about that). Do you really think the bond is going to be as strong? Generally, no. There are always outliers, but statistics have shown that those who are virginal at marriage divorce far less often. I'm not saying that it is impossible to "love" after being passed around and emotionally worn, but it is essentially impossible to love the same as that first indulgence.
