Help me understand my parent's odd relationship

[Waferbiscuit]

My dad and stepmother have been married for almost 40 years but I really can't understand the dynamics of their relationship. Because it's puzzled me for so long I thought I'd ask others for their POV.

Dad is an economist, hard working and very career-focused, very sharp and well read with lots of hobbies. Interested in the world - reads newspapers every day, lots of books on the go and very keen on politics.

Stepmother is the opposite. Does not read, no hobbies and has very little in the way of opinions. She has no friends - genuinely. She has never worked throughout their marriage but because they are well off she has had a housekeeper so she doesn't have to fill her days with domestic tasks. She spends the day shopping or getting her hair done or watching TV and now that they are older she doesn't go out at all. Dad looks after all elements of managing the house (e.g. paying the bills, sorting gardeners etc) so SM doesn't have to.

They have very little in common and I wonder why they are together. Why does he want to be with someone who doesn't challenge him intellectually in any way? Or share his work ethic? And why does she want to be with someone with whom she has little in common? What do they talk about? Their relationship seems so surface and I have never heard them have a 'meaningful' conversation about anything deep or considered (I know I'm not privy to all their conversations but I have been around them a lot.)

For years I've judged my stepmother for being a bit vapid but increasingly I judge my dad for keeping her in her cage, for choosing a life partner - perhaps a 'trophy wife' - who just provides some kind of easy comfort.

Is this a generational thing? Are my parent's generation happy to choose a life partner based on simple companionship and they have limited expectations beyond that?

I know it's 'not my business if they are happy' etc etc so please don't post that. I'm just genuinely perplexed as to why they are together and how long they have stayed together. Would love to know thoughts from others/if parents are similar.
