Among our friends I can think of at least three immediately - partnered accountant (f) + teacher (m), some senior executive at a f500 (f) + professor (m), senior auditor (f) + line chef (m). The former two going for 5-10+ years with multiple kids, etc. Probably could think of more if I asked my wife, because I don't keep track of who works where. I think you were correct up until somewhere around 2015-ish, when there was an inflection point on who marries down more often (now it's women marrying down more often than men).
