Hi UBM101, Ditto what ignat wrote. I feel that you need to discuss how you feel with your husband and the best way to approach his parents. If he does not agree with your approach and feels that he can convert you with time, then you are in for a very difficult marriage.
If your husband asks you, "Why you will not become a JW", I would tell him to read "Combatting Cult Mind Control" for himself and give him your copy instead of asking him if he really wants to know.
I wish you and your husband a happy and wonderful marriage free from the WTBTS's BITE Control.
Peace be with you and everyone, who you love,
Robert
