Your husband who took low-wage jobs to pursue educational pursuits didn't not work and rely on you to financially support him. Regardless of you making more than him (I assume, from a 40+ hour/week job), he was still making something and being as self reliant as your situation allowed. You sacrificed working to that degree for his benefit. That's admirable. The difference between you and him, is that you don't now work a low wage job. You have no job. You are completely financially dependent on him whereas he was never completely financially dependent on you. His income may permit your current lifestyle but my opposition to being completely financially dependent on another person, except for where one (either the male or female) is taking care of young children, has not changed because of your example.
In the end, you shouldn't care what your family or friends say if you're happy. Don't assume that everyone who oppose your lifestyle is envious. Some people actually enjoy the liberation of sustaining themselves and not having to rely on anyone else. Being married isn't a pass to become dependent, in my opinion. Working together does not mean that someone else has to support you, except when necessary. I don't label housewife as lazy or gold digging but as dependent. I don't like dependent men or women. Even if I were married to Bill Gates, I'd still have my own source of income and only when MY choices, whether career or investment, strike gold would my definition of dependence change.
