Hey, there. I'm a regular Christian married to a JW. The big revelation for me is that there are two personalities living inside of every JW. One is the natural person who can laugh, play and be reasoned with. The other is the put-on cult personality. It's a waste of time arguing with the cult personality. They all sound alike and they all answer the same. I could probably repeat word for word some of the things your husband said. Also, the more defensive the cult personality becomes, the more it subsumes the natural man. You end up with a snarling robot of a man sulking around the house.
I learned all this from Steve Hassan's material. http://www.freedomofmind.com/ Learning to recognize the two personalities and how to deal with them has really helped.
My husband is still a JW and I'm still a regular Christian, but there are far fewer arguments. He's about reconciled that I will never be a JW, and he does not put pressure on me to conform. He skips meetings and service more often, and I get my regular man to play with.
It does not work to directly confront a delusional person. If it worked, the insane asylums would be empty and there would be no cult groups. Learn how to address your natural man and bring his personality to the fore, and I guarantee you will have a lot more fun. Besides, natural people are the bane of elders trying to enforce the company line.
