The abuser I had a relationship with definitely wanted power and control. He wasnt physically abusive; what he wanted power & control over was his partner's interaction with other males.
Anything that made him feel.like he didn't have any power, specifically any control over my interaction (or potential interaction) with other males made him at best anxious & uncomfortable, at worst very angry, ranting, berating, critical, and threatening tonend the relationship or implying he was ending it.
He focused on two things - firstly, separate socialising; tried his best to persuade/brainwash/pressure etc me into agreeing to bo separate socialising.
(Even socialising or attending things together however still led to the occasional berating/criticism if he judged my interaction with another male to be somehow inappropriate (talked to long, was too familiar, didn't jnclude or centre him in the conversation, was too helpful etc).
Secondly, I suspect, he was engineering a way to get me out of the work force, by suggesting I work from home, in one of his outbuildings (converted to an office).
I have a vague theory that the kind of possessive, jealous, insecure, domineering behaviour he personified (which is very common among a type of abuser) is a sort of primitive/evolutionary "mate guarding". In that you want to stop any potential other mate from seeing, distracting, seducing, removing etc your mate once you've got them. Including impregnating your mate while you, if the male, may not even find out.
It seems like that sort of territorial, domineering, controlling behaviour might actually be effective, from an evolutionary/reproductive standpoint, because it does make it much less likely they'll be "taken" by someone else or be impregnated by someone else.
Obviously it makes the mate stressed but they don't care about that.
It was probably easier to get away with in the past, and is still normal in some regions around the world (eg in the middle east, and some developing countries). Its only in more modern times probably that people highlight it as wrong and these people (usually men) have an obstacle to behaving that way.
