Hi June Bug welcome!
I am a fading JW and one of the issues that I had hard time to accept was the refusal of blood transfusion. I have an 8 yr old son and should he need blood taransfusion in order to survive I would definitely go for it. Your man might be reasonable and understanding now but once he becomes an active JW, he will be turned into a human robot that takes in everything the WBTS teaches. Please do a thorough research on WT and if possible talk to EX JWs to get an inside picture on how the organization uses mind control on it's members.
