So a gaslighting convo might go something like:
you:'hey I'm not ok with you calling me a bitch'
'yeah? Well you did a, b and c to me' (irrelevant stuff from years ago)
'but that was years ago and you I didnt mean it like that. And we're talking about how it was hurtful for to call me a bitch today'
He looks at you as if he just.doesnt.get it.
You feel the need to explain it to him more/differently
'Anyone would find it hurtful. It makes me feel like you dont care'
'You are always overreacting. I was only joking anyways. Cant you take a joke?'
You start to feel like you just havent explained it right. If you did, he would understand how hurtful he had been...right?
He continues: 'I said it in a joking way (he didnt). I think you misread me and misderstood'
Did you...could you have misheard, you wonder?
So what was wrong with that convo? One, you should never have to explain to someone WHY calling you a bitch was wrong or hurtful. Two, there was no appology. Three, he tried to reverse it onto you and make you the bad guy by bringing up some perceived slight from your past which may not even have been relevant. Four, he tries to convince you that you're feelings arent valid and you are overreacting for being upset at something anyone would be upset by. And five, you are left questioning your own judgement. ...oh and 6, the fact that he called you a bitch in the first place.
Perhaps he throws in some choice sentences like 'I'm sorry YOU feel that way' (this does not mean the same as 'im sorry'). Or 'I never actually said that' or 'are you on your period?'. All if this is designed to make you question your own sanity. So that you stop looking at his abhorrent behaviour.
