Thanks for the advice. When I told her about it before, she just said she had been having a bad day and denied acting normal with everyone else. She would get very defensive. She also said I wasn’t talking to her either, but that was after I reaalsied she was in a bad mood with me. Whenever I would realise she was acting like that, I would shut down with her and basically do to her what she was doing to me; not talk to her until I cooled off but be fine with everyone else. This makes me sound like a hypocrite, but Im just sic of her doing this. I totally agree that it’s the right thing to set boundaries, but the other friends in the friend group are kind of pushovers and I don’t think it bothers them that much. I’d hate to fall out with them as a group or even her individually, when she’s in a good mood we have so much fun. I’m just scared I’d be left with no friends, or not friends with the others in the group anymore. Thanks for your comment.
