What are the unwritten rules of online dating after a long relationship?

[HannahL]

I recently re-entered the dating scene after a long-term relationship and am using a couple of apps, but I'm genuinely confused by some of the current norms around online dating etiquette, like how long to chat before suggesting a meet-up, how to gracefully decline someone after a first date, and whether it's acceptable to multi-date in the early stages. I want to be respectful and transparent but also don't want to overthink every interaction. For those who are navigating modern dating apps successfully, what are the unwritten rules you've found to be most important? How do you handle the ambiguity of 'ghosting' versus a polite rejection, and what's your approach to maintaining safety and managing expectations before meeting in person?
