I'm still very close with like 4-5 of my close college friends. Some I talk to almost every day. Outside of COVID we would have usually gotten together a few times a year to hang, but not this year. I'm friends with a lot of people I went to college with but wasn't really friends with in college, we've become better friends after college... Like my wife. We went to the same college but didn't really know each other in college.
There's a group of friends and we were very close in college, but that includes my ex-gf and after that relationship ended I remained friendly with the other people, but mostly fell out of touch with them. I'll talk to them if we run into each other occassionally, but we're not really friends.
What's kinda funny is that my three closest friends right now are guys who I've known for 30 years, but from like 17-22 or so, we really weren't that close. We became close again in the years after college, and now outside of COVID those are guys I talk to literally every day and see them at least once a month. But COVID has kinda fucked that up per usual. What's funny is like at 22 if you asked me if I was friends with people from high school or gradeschool I would have said a couple but we're not that close, and that I'm closer with my college friends, but ... In the 15 years since then, it's been the opposite.
