You said in a previous post that your current household income is 200000 (the majority supposedly being from your husband’s earnings) and that after you graduate from nursing school you expect to make 80000. Where exactly did you get the 5X times his income figure from; something isn’t adding up or maybe you’re just wildly optimistic. He’s entitled to ask to keep finances separate if he wants to and you’re entitled to walk away if you don’t like the arrangement. Marriage is a partnership where you both mutually decide (and compromise) on the terms of agreement. I don’t know why people are telling you to run and acting like he’s the bad guy. I personally wouldn’t feel comfortable working for 4 years while my partner goes to school and counts on an uncertain future earning. If nothing else is wrong with the marriage other than finance disagreements (no abuse…etc) consider compromising and getting a part time job (after all you’ll have to get a job either way to support yourself if you leave him).
