My friend (31F) is getting really upset with me (31F) because she’s not being invited to my friend’s houses/gatherings but they don’t even know her. A prime example is last month was a friend’s 30th and she wasn’t invited. I tried to gently explain he’s only inviting those he’s close with but she got upset saying they would be close if i’d just take her as my plus one. She then began messaging him over social media for an invite until he blocked her followed by him flat out telling me not to bring her. She then proceeded to comment on every photo/post about the party with negative comments or comments questions why I was dressed the way I was. She thinks because he blocked her he’s clearly a bad person and I shouldn’t be his friend but that’s just not how that works. WIBTA if I just bluntly tell her no they are my friends they don’t have to be your friends to. I feel so childish because this whole situation is silly but it’s her insistence that’s putting others off plus her need to bring up things from the past around people who are strangers to her.
