God - I've heard every one of those !
You're crazy (and that's why he had to have an affair).
It was a joke (after saying or doing something really nasty)
You need help (after he'd done something awful and I got upset)
Telling the children he was 'worried about my mental state, and I might kill myself' - I'd never shown any inclination to suicide.
'I've given 32 years to this marriage, I've 'taken care' of you and the kids, now it's time for some 'me time'
'I can't help it if more than one woman loves me' (when he was having an affair.)
He didn't tell me he was having an affair because 'he knew I;d over react and get upset because of my previously mentioned mental instability.' he really ramped up the 'you're mad' narrative in the six months before he buggered off with OW.
Tables turned when I filed for divorce - I was told ' you will be very very sorry you've done this, I will make you pay'
Narcissists can turn chillingly nasty when crossed.
