Dating is “practicing for divorce”.
Dating is just dumb. It’s kind of like a job interview, people wear clothes they wouldn’t normally wear, go to places they wouldn’t normally go, eat food they wouldn’t normally eat, talk about things they wouldn’t normally talk about; and then if the relationship progresses they eventually wonder why the person is so different than when they were dating.
If one does not have the social skills for a date then they find out real quick whether the dating partner can enhance their time together in spite of this weakness. It may be more difficult for the introvert that is socially unskilled, but for someone who is an extrovert that enjoys drawing out the generally socially shy male who can't stand superficial BS I thrived on dates on those type of men always enjoyed their dates with me--making it worth their time and investment. If they had the opposite experience then they know the woman is not right for their personality type.
Dating is a good thing and a worthwhile ritual. You find out very quickly how well you mesh with another. Also life is made up of socially constrained outings and it is nice to know up front how you and this person operate, enhance, or fail at surfing through that world together. Sometimes two together excel whereas one alone may fail.
