Julia...remember JWs are a FRACTION of the population, like Scientologists. Do not give them power.
Start by planning some nice weekends AWAY from the Borg with hubby. Be accepting. Don't argue.
Make lots of yummy comfort food at 6:30 and his favorite drink before meeting...tell him you are to tired to go to the meeting, and want to go to bed early. If he STILL wants to go by himself..fine...pour a glass of wine and read a nice book in bed.
Mention some basic "DUH" things that puzzle you...plant seeds. Make it EASY for him to miss meetings and have questions. When JWs speak bad about you behind your back to him it will anger him. People are people.
Pounding garden seeds into the soil and watering them with a fire hose doesn't make them grow faster.
Hang in there!
