I can't imagine being married to someone and having something as big as religious beliefs being "out of bounds" for discussion. Simply put, religion should be your way of life and if you live its principals there is no way you could live with someone intimately without your lifestyle which includes conversations, not include those fundamental core values, views and beliefs. Frankly, living with a JW spouse under terms of a "truce" would not be a marriage.
