This may sound silly but the way your H is communicating reminds me a bit of how I am with my WAH.
When I go out of town I don't tell him and if he finds out I am vague with details. I make big decisions and don't discuss them with him but might drop hints about what I am doing.
I behave in this way for many reasons including: -trying to be mysterious -trying to be independent -feeling like I shouldn't reveal information unless he asks -being defensive -wanting my privacy -trying to get a reaction
Obviously I am the LBS and not a WAH but maybe the reasons for his behavior could be similar. To me it sounds like he is trying to take control of his life in a way...
