Don’t know how old you are, but I’m in my late 20s.
My social circle grew a lot bigger when I first moved out, tho I lost touch with many high school “friends”. I moved places again in my early 20s and then it kept shrinking - more adult responsibilities, less friends.
I recently moved countries and my circle now consists of a handful of people I’ve been friends with 10-15+ Years, funnily most of these I’ve met online. We’re all part of the same group mostly, everyone with their responsibilities; wives, jobs, etc.
I’d say that’s pretty normal and expected
