Perhaps what is even more unfortunate is that what you describe here is hardly limited to people in their twenties and thirties, which appears to be the group you’re quoting. I see these and worse in folks much closer to my age, at 67. That means that age maturity in no way automatically conveys emotional maturity. If my dating life (hahaha, that’s ripe) is any indication, some people carry this kind of behavioral bullshit for life. My brother was a prime example of just that. I’m sure I carried my own ridiculous expectations too long. However, failures in love are pretty instructive but only if we choose to see how we are part of or the biggest part of the problem.
