What statistics or records support Flora Dunn's views on expensive first dates?

Flora here. There are a few key stats and patterns that line up with my views on pricier, more intentional first dates:

• In the video descriptions, I reference a survey where 60% of women reported feeling more respected when they clearly stated their expectations upfront. That supports the idea that standards and clarity (including about date quality) change how you are treated.
• Broader dating research consistently shows that when people invest more effort and resources in a date, they’re more likely to view their partner as higher value and treat them with more seriousness and respect.

Would you like sources on respect/expectations in dating, or more on spending and perceived value in relationships?
