Yep Grace is the perfect wife for someone like that - not brighter than him, girlish, happy to be a wife and mother (always talking about making her kids packed lunches), not much ambition, family orientated, religious so won’t go partying/drinking without him, likes to cook and potter around doing not very much all day ready to give him all of her attention when he finally gets home. I hope she finds her own passion and sense of purpose before she does get married, it’s clearly not YouTube anymore. There’s nothing wrong with choosing to stay at home but for her own sanity I hope she finds something for herself.
