Ask your husband what he would do if you had children together, born and raised as JWs, who left to join the army? Or how he would treat his wife who helped her son buy condoms? I am thinking that he might not be the most active, involved witness if he married you, so he might not know that he would no longer have contact with the daughter who left the org and joined the army. He would have you brought before elders and reproved.
Are you aware of what the WT organization (JW's) say about EVERY other religion? Have you seen their latest tract?
