Just read all 3 threads. I'll be honest just the OP posts but 




Sorry you've come across the 30yo mean girls. I wouldn't have believed they existed if I haven't come across them myself.
I have a theory about them though.
Jealousy. You mention numerous times they have it all - happy marriage, big house, new cars etc. But that isn't about what a happy life is.
What you have is strength and a self respect they wish they had.
You had the strength to kick out your cheating ex. Hold your head high. Continue working. Budget and earn everything you have.
You don't need to create drama or gossip and bitch.
Then then think you may be fair game for attack because of this.
When you then stand firm and show you won't engage and back away that jealousy rears it's head again.
How dare you not need them?!
I agree with using cease and desist letter template.
They have no evidence of FB messages and therefore it's defamation/slander. I get confused with which one. They also know how to retrieve messages so they have no get out clause there.
A friend of mine use to throw her toys out of the pram. I wouldn't respond.
She'd then eventually send the apology (but justifying
her behaviour) text.
I'd respond if you really feel that way why would you want to be friends? She'd eventually apologise and start asking to meet up. I with drew and although in contact through text and phone haven't seen her since Xmas.
It's hurting her more than me.
You being aloof will hurt M K and D more than you in the long run. Someone like you will have people wanting to be friends. Meanwhile they'll be stuck in their group of 5 - and the other 4 will always be wondering if their next.
