that said, part of growing up and becoming an adult is seeing your relationships with others change. i'm 32, i'm still on good terms with all my closest friends from high school, but aside from our discord group chat where maybe once a month someone will say something and someone else will reply, we hardly interact with each other because we're generally too busy dealing with shit that's going on in our day to days.
now i'm not saying that they DIDN'T have a fight or something DIDN'T happen, that's entirely possible, but sometimes you just get tired of people, even people who you're close with, and your relationships just cool off.
