Name changed. I'm really hurt by what's happened, and I'm struggling with being told my opinions, which I've never thought are anything too uncommon, are that 'disgusting' (her words) that she cannot continue the friendship. We had a disagreement about a certain subject, which led to her blocking me. A few days later she unblocked me and attacked me with all these messages about different topics, asking me outright what I think as some sort of test, before concluding my answers weren't good enough for her high standards.
AIBU for thinking two close friends, of decades, should be able to have different opinions without cutting ties? I'm not sure I have any choice but to let it go. I'm just angry.
