SugarHut, I agree with you that any decisions which impact on the family as whole should be made with the agreement and/or compromise of the whole family. I can't really understand doing it any other way. Announcing something, fait accompli, to my DH or him to me is just bizarre.
However you seem to be overlooking one crucial aspect.
In order for things to continue as they have, it necessitates the foregoing of any sort of pension, any sort of income, any sort of work experience, any sort of keeping-one's-hand-in, any sort of career progression...
So while the OP was unreaonable to just announce her plans in a 'decision made' sort of fashion, her DH's response reveals him to be somewhat of a buffoon, as well.
I can't imagine being married to someone who would just take for granted me going up my entire career, my years of education, my future career prospects, and my future earnings, in a 'I don't care what you do, as long as the drudge work gets done' wave of the hand.
Sorry, but what an unevolved twat!
You might be happy to be married to such a specimen. One who patronisingly tells you 'he could never do what you do', pat-on-the-head-dear, but others of us are not.
And I must say ... I find there to be something deeply suspect about women who rush to identify with the man/husband in a scenario such as this. It's weird, IMVHO.
