So I was friends with a group of three other women, they were all friends before me and I was good friends with just one of them and then slowly integrated into the group (6ish years ago).
Anyway the person I was good friends (Friend 1) with we’ve just slowly drifted apart. We haven’t spoken this year (I asked to meet up with one (Friend 2?) as I was in her city for work and she made an excuse).
Friend 1 has since got engaged and I only found out because I saw the large engagement party she threw. And the other two friends have gone ott posting about it on social media - countless stories and posting photos (which they don’t usually do). I just text the friend that it was amazing news and congratulations, never questioned why I wasn’t invited.
Anything I’ve posted the other two have looked at immediately (which again they wouldn’t usually do). I know the event isn’t about me, but if they were my friends they would have at least reached out just to see that I was ok, as I know it would hurt them to just not be invited to a big event.
