Author here. Yes, I've used introversion and extroversion mostly to mean the amount of socializing one does, and that's probably not the best definition of those terms because they also relate to energy. And people are not a perfect binary. I've heard terms like ambivert and "low energy extrovert" which I think describe me well.
One thing you said well is how you put in the effort even though it was an energy drain. Because you felt the reward - finding a partner - was worth it. And I have mostly not felt that way.
Author here. First, I didn't claim to by a "raging introvert". But I was more introverted when I was younger and I believe I'd still be like that if I had already found a partner. Also I'm probably using the terms extrovert and introvert in a very sloppy manner to just describe the amount of socializing. I might have better chosen other terms.
Second, I didn't claim that people are only loyal because of lack of alternatives. I apologize if that came out offensive. But I still believe that people are more likely to cheat on their spouse a) the more alternatives they have and b) the more they enjoy the process of dating and flirting.
I'm the author, and I'd like to thank you for this comment. Yes, I have a tendency for overthinking, so that's maybe why it seems complicated. I have thought about the different reasons for why people get into relationships as well and I think you categorized them well. I'm still unsure about my own "why" and that's what I'm trying to explore now starting with this post. Yes, I'd like to have children, but it's not a "burning desire" and it's difficult for me to imagine being a father without knowing who the mother of your children will be. Partnership sounds wonderful, but I'm not sure if a deep connection with a single person is really better than having a broader network of friends.
I'm the guy who wrote the post and I can confirm the number of single women I meet is extremely low - which is what I meant by "lack of opportunities". I do have a somewhat active social life but I would have to actively optimize that for meeting single women, which would require some changes, which I haven't done - "lack of desire". But it's something I want to work on and maybe that's my next blog post :)
