Being told your mother is a narcissist (by a questionable source who has never even met her) has done you no favours, as all it's done is given you an excuse to absolve yourself of all your own horrifying, cruel and vindictive behaviour. What you're conveniently blind to here, is that the apple hasn't fallen far from the tree.
You fall out with just about everyone you make friends with, bleat about how you're the victim, drag the other person's name through the mud to others and online, and set the nastiest flying monkeys you have at your disposal onto them. You nearly destroyed my friend's life TWICE when she was at her most vulnerable.
The people you fall out with aren't the shits here. You project every single one of your vile qualities onto them, and YOU are the common denominator in every bloody fallout.
I doubt you'll ever be made to pay for it, as playing the damsel in distress is a skill you've sharpened like a knife over the years, and people unwittingly lap it up. Your DH enables you to the nth degree, and not only that, embarks on your vicious smear campaigns on your behalf.
You're a nasty piece of work behind that helpless little flower facade. To think you call yourself a feminist too... I sincerely hope one day, you get the short, sharp shock you deserve.
