Yes! I did this. I fell apart from my friend group when I married. I was a few years ahead of the others when committing…anyways, I focussed on work and building wealth to help with ease of living later on. I’d keep in contact with my friends loosely via Facebook. After about 9 years I noticed one friend had stopped wishing me happy birthday and Christmas which was just something we did. 3 years later of the same thing I reached out to other people to see if he was ok…got lots of dead ends, old stories of arguments he had had…found his sister that had kind of estranged herself from her family and married and changed her name and moved to the opposite coast. She passed my number onto him and told me he was doing ok. Later on, he reached out and we had a good chat and planned to meet up. This happened just after the first major wave of covid. We met for about 4 hours and he talked about himself the whole time. Not once asked me about me and my family, how I was doing… haven’t spoken since. Your mileage may vary
