Yes, supermommy, you must be resolute and absolute. They will not stop until you make it firm. They will keep coming and coming and coming as long as they think they have an opening. It sounds like your husband is a nice guy and they see an opening to get in through him. It is also your husband who must tell them to stop since it is he they are targeting now.
My middle daughter, Nancy, age 15, was studying with an older sister, Carol. Nancy came to me and said that she no longer wanted to continue the study and wanted to tell Carol at the next study. I said, "OK, what has brought you to this point?" She told me it creeped her out how that Caral at the last study, kept overstating how important it was for her to stay close to the organization, over and over again. The over-emphasis made her suspicious and leary and many of the things I had told her started to make sense. The only reason why Carol did not continue to pressure Nancy is because I kept showing my face, and Carol will not try to go through me because I now have a reputation of getting in JW faces and getting my point across.
Be firm, and direct. If they start asking you questions, take control of the situation by asking all the questions . He/she who asks the questions has control of the conversation . What do I mean by this? If they ask you a question, simply pick your topic and shoot a question right back at them: What is the Wild Beast? How are we to view the Wild Beast according to the WT? What about the UN membership thing? What can you tell me about that? How does the GB rationalize this? You will have them running before you know it, but keep control of the situation by asking all the questions . . . it's an old salesman's trick and it works. To be forewarned is to be forearmed, so share this with your hubby too.
Good luck to you both and keep us posted as to what is going on.
