"full of speculation and no knowledge of the reality."
1. Are you disputing that women are becoming more highly educated relative to men and becoming more independent?
2. Are you disputing the reality of female hypergamy?
3. Are you disputing the reality of an increase of older, childless, and single women?
Those are the main points I made.
Your specific anecdotes of what occurred in your marriage, personal feelings about these truths, or personal preferences neither address the points I made nor refute these broader societal trends.
