Hi Linda, sorry can't help with meeting people, we tend to keep ourselves to ourselves.
We do visit Nerja regularly plus nearby villages of Frigliana & Torrox, always plenty of English voices in the restaurants & shops, even now when very few are holidaying from UK.
There are English supermarkets in both Nerja & Torrox Costa (5 miles), they wouldn't be there if there weren't local UK customers. We visit the Torrox one, run by English people. Can't remember if they have a contacts/events notice board but might be a place to start meeting people.
