I can't read your mind, but I can attempt to speak to a few of the situations that may present. This is the stereotypical seminary set up. Man go to school. Woman work hard to pay. Woman has baby.
Woman works for baby and for boss.
There are indeed a lot of families on campus where the wife is not a student. There are advantages to this. For one, there is probably less of a financial burden with the wife working while the husband is in class. Less loans mean more money when a family is started. It is a great way to do it.
