Hey Op, I have just read the whole thread(s) I have been utterly gobsmacked at the whole sorry tale. I honestly don’t understand what C is telling people. Her husband is also a spineless twat, he has the absolute capacity to clear your name and remove you from their sordid pathetic relationship and yet he bows down and goes along with it, what a guy!
As a pp said, the whole scenario smacks of C having NPD. I also agree with the pp that said they all enjoyed rescuing you when your marriage broke down. It’s not an equal friendship based on trust, love and respect - meaning that I honestly feel you’ve lost nothing by not being part of their “clique”.
I would have my head held so so high, I wouldn’t turn up late with headphones, I wouldn’t be breezy - I’d join the PTA and get involved in all aspects of school-life, I’d make my myself “open” and approachable to other mums.
Because, this way people will definitely ask you what’s gone on and I would have a one line blanket statement for all
“Oh yes, C thinks I’ve been fucking her husband” and then laugh. Look at the shock on their faces and respond with “haha I know right!, have you seen the state of him”
I would smile at K,L and D and say “Hiiii” as I breeze on by, look down on those little Gretchen Weaner sheep, pity them openly and stare at them - do not put your head down, do not look away - hold your head up high.
And, bide your time - this will eventually all come out. At the moment C looks like a complete doormat, her husband is back there right? Her fake, unstable world will come crashing down.
