I agree with most of this, but a few things to note;

-Interest could have been there initially, but then depending on how the dates went, it waned. Many women have been socialized to be "nice" and they are too scared to overtly reject a man, so they go along to get along. I see how that can be perceived as feigned interest, but it's worth noting that their intention was not so much to get a free ride, as it was to "spare feelings"

-There are definitely women who accept dates JUST for the dinner. However, at what point does the onus fall on the man to be more cognizant of "reading the room"? Suffice to say, these two are not just communicating for the sole purpose of meeting up. Is there reciprocated interest in getting to know him? At some point he has to sharpen his emotional intelligence to weed out viable mates, from women who merely want to be fed.

-Timing is everything. I might feel a connection with a man and be genuinely interested in him, but I will still exercise self-control and hold off a bit. Sleeping with a man "too soon" is a legitimate concern and we are old enough to know why, so that needs to be taken into consideration as well.
