>if you mattered, you would've gotten a direct message or call from them.
That ignores the asymmetry of a lot of life events. For example, if a parent died, I'm not going to call everyone in my life to tell them, I would have more important stuff on my mind. I might post it on social media and then the onus is on other people to reach out to me. And if someone doesn't reach out, it will hurt the relationship a little even if I'm not conscience of it because when I think of people who were there for me during a tough time, the friend who never knew my parent died wouldn't come to mind.
