Assalamu Alaikum,
Two things:
1) Just because you've talked about something before marriage, doesn't mean it will actually end up that way after marriage. So saying, "talk about it before marriage" doesn't magically guarantee that it will not be an issue later on.
2) "Ideally"...way overused and no such thing exists
There are a million career related scenarios that can arise after marriage. Put Allah first, communicate and share how you feel with each other and insh'Allah you'll both be fine.
