As someone who is right on the cusp of Boomer and Gen X, and now in my 50s, I’ve realized a few things: I think some of the things you describe are certainly generational, but much of it is age. I think many of us can relate to a lot of what you are saying and have felt and done when we were younger too.
We all do stupid things when young and want to be liked and loved and want to feel a certain freedom. Most young people, no matter what generation, are trying to figure themselves out. As we get older, we do indeed get wiser, but we also get more cynical. And most of all, we get tired. I’m just at the point now where I just don’t care about romantic relationships any longer. And I don’t care about making generalizations. I take every human as an individual, knowing also that those individuals can be shaped by all sorts of things.
What’s really happened as I’ve aged is that I’ve made a very important choice: I have chosen me.
