I'm in a group of 5 close friends. Before the pandemic, we would meet regularly for meals/nights out/BBQ's etc and talk regularly on social media. Since lockdown, we went out once when allowed but as a few of the group are considered vulnerable, nights out stopped but I've met with one out of the group who i'm the closest to since.
On birthdays, we usually message each other happy birthdays and post on each others SM, but my birthday was a few weeks back and apart from one wishing me a happy birthday, I've heard nothing, not a peep from any of the others. In previous years I got messages and posts on my profile.
AIBU to be upset by this? I considered us a close friendship group. I wonder what happened.
