It’s an age-old dilemma: How soon is too soon to get in touch with a romantic prospect? Does it differ depending on whether it’s after you’ve met, matched on Tinder, been on a date or hooked up? And how long is way too long to leave it before striking up some form of communication? It’s a constant tension between appearing overly excited and coming across as aloof or even rude, and it can be difficult to know where to strike the balance.
