> he would not be able to provide for her
he only asked about dating, not marriage
students who can't provide for each other can still date each other
also, modern society is a bit more accepting of reversed gender roles. the older partner wouldn't be bothered by it, though the younger partner would probably feel inferior regardless of their gender especially if they are still a student - that's just how the power dynamics go.
their stated concern about age gap is universal: your tastes and hobbies would be different. you'd have some things you've grown out of and developed a distaste for, the younger one has just gotten into it. forget trying to provide for the younger one - you're gonna resent each other eventually!
