You could try calling them or seeing them in person. If they refuse to interact with you unless it’s documented on Facebook are they really people worth interacting with?
Arguably for 1-on-1 relationships, but even then it would mean losing some not so close friends, that I still enjoy seeing once every 1-2 years.
But at times it's impossible in practice: my friends will create Whatsapp groups for instance to plan vacations/batchelor parties/random events, and I need to use that if I want any meaningful involvment in the event.
I've sometimes been passive and just showed up, but I'm losing a part of the shared experience.
