Tell her to speak to a Rav. I think it says in Pirkei Avos “asei l’cha rav” and not “asei l’cha message board”. But don’t quote me on that because I have a really bad memory so I could be wrong.
On another note. It’s possible to work without a degree and send a husband to kollel. But its very hard and requires a lot of mesirus nefesh. I know some people who are doing it that live in the red (while I also know some that did find good jobs and are above line too). It really requires knowing yourself really well and I think its a lot harder for girls than for guys.
