Why don't Cypriots behave more like Greeks anymore?
Let's set aside for the moment that this is a crude leading question, and answer it with one possible answer : because Cypriots were not Greeks to begin with. Some Cypriots spoke Greek, some Cypriots spoke Turkish, some Cypriots spoke other languages and some Cypriots spoke more than one of these languages, all varying across the centuries. Equally some families spoke Greek during a generation and later that family spoke Turkish, and vice versa, and other combinations of languages across the centuries. Similarly some families were Orthodox while others Catholic, others Muslim, others Armenian others quite irreligious. All very messy, not at all neat, and never is there a pristine thread through the centuries.
