No matter what you it's never enough. You could be literally perfect in every way and give into their every whim but it will never ever be good enough. They will always find something to nitpick, criticize, become enraged by.
It's not actually about the woman being controlled and her actions, it's about the abuser. He centers himself in everything and every aspect of her life and their shared life. He sees her as an extension of him, not a human with individual agency, decision making and flaws. She should feel and think exactly as he does. If she doesn't then that's an issue and the emotional abuse starts. He probably isn't even conscious he's doing it as it's so engrained. So there is nothing she can do or say that will be enough and that will end the cycle, she will always do something 'wrong'.
He also will change the rules and the goalposts to suit himself, keeping her constantly unstable and never really knowing what reaction she will get. And the most innocuous things going about your day can kick off a massive temper tantrum as she should magically know what he's thinking and feeling that day (because he sees her as an extension of him).
He's entitled to her time, money, body, emotions. And any slight deviation and flaw turns the anger towards her as he couldn't possibly be wrong or have flaws, eh.
It picks away at her sense of self and confidence until she's doubting her decision making, and abilities. It's so insidious.
Of course, if he was just a blatant horror from the start then she would say fuck toy and walk away, so the skill is in luring her in, love bombing and putting on a pedestal then slowly and subtly he chips away at her, he probably isn't doing it consciously but it's ingrained pattern of behavior treating women. And she is probably a people pleaser so accepts the little warning signs and doesn't realize til it's too late.
The boiling a frog analogy applies here, if you throw a frog in boiling water, it jumps out. But if a frog is in cold water slowly heating up it doesn't notice til it's boiling and it's too late.
How do I know this? I know this as I'm a smart, intelligent woman who is in this exact position and is trying to summon the resources to leave.
