My mother, who is NOT one to give advice, once told me, "Make sure you will be able to take care of yourself if you need to."
I have two daughters and a son. I hope, and actually expect, all of them to go to college - and graduate. I want my children to be independent and to be able to sustain themselves. That said, I am also teaching my children that marriage and family is the ultimate goal.
I met my DH when we were in law school - the first day of law school. We were married after my second year, but I didn't stop going to school. My education was important to me, as important as my DH's education was to him.
And my education still matters - I am still a practicing attorney and homeschooling on the days I don't work. And I hope that I am teaching my children (especially my daughters) that you don't need to give up on your goals - if you have a goal to complete your education by getting a college decree, or a graduate or post-graduate degree, then do it; but be true to yourself. If one of them has a goal to be a full-time stay at home mother, then I will support her fully. However, if one feels as though she wants to devote her life to her career, it would be with misgivings, but I would support her as well.
