Some JWs , especially those "brought up in the truth" become very clever at compartmentalising their lives , especially if ( like your husband ) he is a weak JW who has married a "worldly" person and has no privileges. I grew up as a JW & saw numerous kids doing the "double lives" act. I still have a chuckle today when I hear people saying what a "spiritual person" so-and-so is. If only they knew.....
A mate of mine is an elder , but when with his work associates he swears like a trooper , tells a few dirty jokes & is indistinguishable from them. But put him in a suit & he adopts a completely different persona when giving assembly talks.
Hypocritical - maybe. Not all JWs are like this , by any means. But remember that being a JW is all about appearances - giving a facade of Christianity - and many adopt , consciously or subconsciously , coping mechanisms that allow them to survive.
