Actually she is the one who unfriended me because she does not want to read my posts and see how much fun I am having (her exact words).
Now, the more interesting concern is if I should unfriend my long time friends (close friends I have known for over a decade) because they continue to choose to maintain a close friendship with her despite knowing what I am going through.
They also leaked all my private info to her and I am unsure if they will do that again in the future. In addition in FB if they comment on my post I believe it would be visible to my ex as well even if me and ex are not friends.
I thought the best thing is to unfriend the friends as well since I want no connection with my ex whatsoever going forward.
