I moved away from an area several years ago and from the start only stayed in contact with a handful of people from a very large friendship group that I had been on the edge of.
After a year or so it was obvious which people were friends I could talk to, which people only kept in contact because we had friends in common, and which people were never the first to contact me.
In the end I only stayed in contact with friends I could talk to. I actively avoided a few others and just sent polite, short replies to others.
The years passed. I realise now that staying in touch with some friends but not with their friends has made things a bit awkward. I think I was unrealistic to imagine it wouldn’t be an issue.
