"Feels like you're making the assumption that she needs to balance each observation with a "winning point" about herself."

I make no assumptions as to what Debbie Weiss "should" do. Instead I have made an observation regarding something she did not do. I leave it to each individual reader to interpret for himself or herself the significance of that omission, as you have done for yourself

"...you're correct, no one is obligated to meet anyone else's expectations."

Then you and I are in agreement on that point.

Ms. Weiss has described men who fail to meet her dating expectations as "immature." That is a characterization that implies a deficiency that needs to be corrected.

Ms. Weiss is not entitled to a man who meets her expectations.

Fortunately for her, as she states in her article...

...she has found and wed a suitable suitor.

I am, therefore, curious as to why she is concerned about the so-called "maturity" of the remaining members of the male population. One logical answer is that she is admonishing the male population for their failure to conform to her expectations and considers them obliged to do so. To what end I cannot say, but I could venture a few guesses.
