NAH. There are endless stories about one spouse financially supporting the other through school only to find themselves tossed aside after they graduate and get high-paying positions.

There are also endless stories about one spouse doing all of the household chores in addition to paying all the bills while the other is in school and studying.

It's understandable that you have a goal, but it's also understandable that she's concerned about being used and left with nothing to show for it.

If the two of you are going to make this work, you need to address her concerns and come up with a realistic plan that's fair to both of you. A post-nup and fair division of responsibilities could work, but it needs to be realistic and needs to protect both of you financially.
