The unfortunately titled book, Why Men Don't Listen and Women Can't Read Maps
(I know! I almost don't want to recommend it, but it's good!) may provide some insight into how your husband processes things. It sounds like he just needs some time and space to consider things.
It also sounds like YOU need a hobby. That sounds snarky, but really - why are you worrying about something that may or may not be a problem in the future? If everything is fine now, BE in the now! Accept your husband, and enjoy it!
