Hi
@Maggie/Magpie - I agree with what Brunneria says, above.
So sorry to hear that your friend's reaction has been so negative. It sounds to me as if her somewhat angry response was based on embarrassment, hence the denial and she's defending herself by protesting she knows all about it & pushing you away. I suspect that underneath the bossiness, always has to be right, being the centre of attention (by hosting events and organising everything), and now cancelling the quiz, and your regular lunches, she's really a very insecure person underneath all the bluster. In which case, if that's true, she may find it very difficult to approach you when she's come to her senses. Give her space - yes, absolutely. Depends how much you want her friendship (and perhaps that of the others in the group) whether you keep the communication lines open, and for how long. The longer it goes on the more difficult it is to break the ice & heal the breach - so, it may come down to you making the first move towards her, even though you've already done so once. That does
not mean you give way, nor concede anything - you've made your point, stood your ground, and she knows it.
