Something's profoundly wrong when people put so much importance on what is an externally mediated measure. I don't know what it points to other than a sort of spiritual void, but the status game is one you are statistically almost guaranteed to lose.
It is the thing I hate most about my 30s and 40s: the utter seriousness with which status is regarded.
There are some sad stories in these threads.
I just want to add that not all partners are like this.
But the ones we attract in certain parts of our lives are definitely prone to it! When our self-identity (or at least our time and energy) is wrapped up in material success, or job prestige or some other externality, we attract people who agree with us.
It's a delicate edge, because most of us want to build, accomplish, achieve something that makes us proud of our efforts, and we dump a lot of that into "work" in our most-eligible years.
So if we "succeed", or move toward success, we attract those that see us the same way we imagine that part of ourselves.
And then the rest of life starts happening. I want to live in a van and see the national parks! I want to take the modest exit and move to the Caribbean. I want to get a dog and stop running in place in BigCity. I've saved enough and don't want to deal with issue X. Etc.
This new status is not always met with the same enthusiasm as the climbing part of our journey. We created the fiction, so maybe it's not completely fair to be disappointed when our focus shifts and theirs does not.
(I don't mean to suggest that I know anything about your life, I'm just riffing on your last sentence.)
I can't recommend this enough!
