He's made contact again from a flight (the joys of wifi!). He makes a living from travel blogs.

My friend decided to see what would happen so reopened her side of communication. His latest message asked "don't you miss our chats?" Her reply, not immediate, was "yes but you have a wedding to plan". No response, even taking into account the time difference.

Reassured me that she won't do anything daft like spread his name over social media. Apparently, the waitress did ask if they wanted to split the lunch bill. My friend said yes, then he responded that it was "on him".

One of my contacts, who's always been very respectful with me, described social media as no place for shrinking violets and a cesspit at times. How true!
