You can't depend on anybody to support you.
Your husband can die or just become unable to work for whatever reason (unemployment, illness, disability) or you might get divorced and yes, it is women who get screwed over financially because of divorce. Getting back into the workforce is much harder than it seems too.
Don't ever sacrifice your financial security for the sake of a family. It's very possible to raise kids and have a successful career too. Maybe you can cut back your hours or work from home or whatever... but it's possible. And if you don't have kids, then there's no reason whatsoever to stay at home.
