Back in my 30s I would typically see some combination them - all of us were single - 2 or 3 times a week: in the pub, dropping round, out to see a film, out for a meal, poetry society, wildlife volunteering etc etc.

A couple of decades on I am married but they are all still single. They don't see each other nearly as often, it seems, but I'll meet them as a group only once every couple of months. I may meet one or another for some reason every few weeks though.
