In this episode of "Dear Matchmaker," Cat addresses three key pet peeves in online dating. First, she advises against demanding confirmation on the day of a date, arguing that it stems from insecurity and fear. Second, Cat discourages putting pressure on potential future dates immediately after the first encounter, suggesting instead to give both parties time to process and reflect. Finally, she advocates for presenting one's best self in online dating profiles, likening it to preparing for a job interview. Cat's advice centers on fostering healthy communication, setting realistic expectations, and prioritizing self-confidence in the dating journey.
