I certainly don't think status indifference is universally problematic, but was trying to point up the difference between "I've figured out that the people in my social circle/the norms I've been using are vapid and petty and I'm ready to move on with my life" and "I'm no longer inclined or able to participate in activities I find meaningful."

The discussion, as I read it, had been about using fashion to attract partners and then giving up on being fashionable. In this case, I posited someone who started dressing fashionably specifically in order to attract partners and quits dressing fashionably when they've done so. Maybe they've had a revelation of the "my norms are vapid" sort, or maybe they've just accomplished their goals.

But thomblake had an implied question about whether anyone would actually leave a partner because the partner looked unfashionable. One possible cause could be that what made them initially attractive were other character traits/personality features that also led them to dress fashionably, in which case the partner might be have good cause for concern (the "no longer able to do activities" situation). P(!traits | !fashion) > P(traits | !fashion). So the other status gains I referred to would increase the estimate of P(traits | !fashion).

One wouldn't leave a partner for no reason other than unfashionability unless one places such a high value on fashion that no other status gains could make up for its lack. But a partner who suddenly quits caring how they look might send up some red flags. (Absent discussions of updating norms, of course.)
