Very interesting.
Keyword = "crush" = brief description = "this person considers the referenced person to be a crush (i.e. has a crush on the referenced person)"
Keyword = "date" = brief description = "this person considers the referenced person to be a date (i.e. is dating the referenced person)"
I'd argue that considering a person to be "a date" does not imply that one is dating that person.
