How do you know when not to have a second date? ๐Ÿค” Todayโ€™s date was actually really nice. We chatted for around 90 minutes, but by the end I just wasnโ€™t sure I felt a romantic connection. Now Iโ€™m wondering whether thatโ€™s enough to know there shouldnโ€™t be a second date, or if sometimes attraction takes a little longer to grow. Am I giving up too soon, or is this just how you know? Iโ€™d love to hear your thoughts. #Dating #FirstDate #DatingAdvice #DatingLife #Overthinking
