accessory human?

I'm watching a young couple's youtube videos and noticing that the woman seems to focus almost entirely on being the man's pet.  She's being cute, but she doesn't seem to take a lead in anything, do much active helping, or have many skills.  Now that's not because she is stupid, or less able, but because she's being a girl for her man.  He's accepting the helpless behaviour because he thinks that's what girls are like.  Could even be it's what he wants from her, because it makes his ego even bigger.  He's the one who can drive, plan routes, make decisions, figure things out, the capable one.
So she's a pet, an accessory. If she fails to amuse or comfort him sufficiently, she has no value!
I know he wouldn't agree nor would she, but I suspect a lot of relationships are like that.  So eventually the woman matures and gets tired of playing pet, as grown adults will.  Then what? So often, then divorce.
I wish we wouldn't keep teaching our men and women that women are men's accessory partner, a pet, a toy, a place to go for oxytocin, and nothing more unless she gets pregnant and takes the role of mother. Something even animals do without any brains at all, they think, so it doesn't prove, no matter how well she does it, that she's a person either.  The way women talk when they're bunkered down in a kitchen making school lunches tells me they feel it keenly.
