Does anyone else just stop talking to a friend?

To add context to the title I’m talking about how I’ve only ever really had “school” or “work” friends. I never really hung out with people outside of work or school so when I’d make a good friend there at some point we are going to stop seeing each other. I just don’t make the effort to text or call them after that. I guess I just feel weird doing so and I don’t like hanging out with just 1 other person. It needs to be with a minimum of 2 other people or else I’d feel uncomfortable and not have as much fun. So we stop talking entirely. Do any of y’all do this?
