A date is like art. If the intention is that something is created to be art, then it is art. It can be bad art, but still art. So if two people get together with the intent that it will be a date, then it's a date. If there isn't a clear understanding that it will be a date, then there can be a misunderstanding. That's how your friend can sincerely believe that she hasn't been on dates with her ex recently, while he almost definitely believes that these were dates. She will probably be surprised and unhappy when he makes his move soon.
Good decisions come from experience. Experience comes from bad decisions.
