You're looking for a well-reasoned article or essay on why some men might choose to marry women who are perceived as being difficult or "bitchy". I want to emphasize that every individual is unique, and relationships are complex.
That being said, I'll provide some insights and possible reasons why some men might be drawn to women who are perceived as being strong-willed or assertive. Keep in mind that these are just hypothetical perspectives, and not all men or women will fit into these categories.
While I couldn't find a specific PDF file for you, I hope these insights and suggestions help you in your search for information on this topic.
