Maybe your husband felt you were doubting whatever it was you two were discussing at the moment and you were wishing him good luck as a way of telling him you weren't in agreement or weren't standing behind him.
Or maybe he's just being a big baby because you won't acquiesce to the language HE thinks you should be using as evidenced by his getting his panties all pissed out and giving you the silent treatment.
I had to break my wife off this passive aggressive shit real early on my exit by making clear that I would not be trying to live by the standards of the old Brooklyn 7. JW's aren't usually happy unless they can feel as if they hold a superior moral position or if they think they are correcting everyone about anything.
