I can’t speak for the entirety of France but if you’re looking for expats in Provence here are a few suggestions.
When I first moved to France I had it in my head that I would only meet French people. I soon learned that in the countryside, meeting any people was a bit tricky. Throw into the equation a lack of funds and a lack of confidence in my French skills… Let’s just say I didn’t make many friends during my first couple years here!
People in Southern France are known to be more closed that people from the North. I’ve known of even French people who move here from other areas and have trouble. Small villages can be the trickiest. Where everyone has grown up together, they’re not jumping to make new friends unless they have a particular interest in speaking English.
After two years, I accepted the fact that I need to do some serious reaching out to other expats. People that have moved here from abroad will automatically have common ground with you. They will often lead to French friends and tips on where in your area to seek friends.
