I have read every comment and just want to say that this thread is the very best of why mumsnet is amazing. It’s just so reassuring to read about other brilliant, kind, intelligent women who have also suffered exclusion as adults and the different strategies and advice.
I was given the cold shoulder by a friend who I really liked who was part of a wider group, she stopped speaking to me and then started organising things without me there. It honestly really shook me as previously to this I had never lost a friend in this way and it made me doubt myself so much. I honestly had a bit of a dark night of the soul for a year or so.
I am incredibly lucky in that I have a really generous number of friends and the group I was cut out of was never my “main” group of besties - but good god it hurt and really effected my self esteem.
But at the same time, I do see it as sort of a lesson - I had a few years of being included by everyone and well liked and the danger of that is that your self esteem becomes linked to validation from others. If you’re not careful you start to lose yourself and make decisions based on “fitting in” rather than your own values.
Even though it made me less trusting of friendships (would never have predicted that this woman would have dropped me and not at least let me know what I’d done wrong, so it does make me see all friendships in a new light) it also has reminded me that my sense of self must come from within. Even if the whole world turned against me, I would still need to love myself - so the opinion of one woman or a group of women should never be enough to shake me ever again.
In terms of practical next steps though, I think best option is to reach out (perhaps call?) the friend you are closest to and say how hurt you are and ask if something has happened. In this situation you really need to divide and conquer rather than communicate with them as a group.
In might transpire that it’s one or two of the group that don’t like you for whatever reason - but there are 7 of them right? So you find the 5 that do like you and you just cultivate those friendships - you make your own little breakaway clique and stop bothering with the ones that don’t like you as they’re not your tribe and they don’t matter.
