In one short comment she mentioned they talk a number of times during the day, each day. Sounds like a good relationship.
She advises him on things. That’s good. She also says she disagrees on things too. She wasn’t just showing submissive side. She has brains and opinions.
Yes, this does sound like a good marriage and she doesn’t want to be in SOCIETY, as Ivana did ( which ruined THAT marriage ), nor is she flighty ( which Marla is ), so so far, so good.
