I doubt if they would take any action, especially if your husband has never been a Witness.
If you did, you could always use the Biblical example of Naaman. Naaman was a non-israelite who was cured of his leprosy by Elijah. He becomes a worshipper of the LORD but has a problem. The following is an extract from the account in 2 Kings 5;
said Naaman, "please let me, your servant, be given as much earth as a pair of mules can carry, for your servant will never again make burnt offerings and sacrifices to any other god but the LORD . 18 But may the LORD forgive your servant for this one thing: When my master enters the temple of Rimmon to bow down and he is leaning on my arm and I bow there also-when I bow down in the temple of Rimmon, may the LORD forgive your servant for this."
19 "Go in peace," Elisha said.
The problem with the Witnesses is they judge people rather than trying to understand them and their individual circumstances.
