Welcome monis , If you haven't read Steve Hassan's books (i.e., "Combatting Cult Mind Control", "Releasing the Bonds: Empowering People to Think for Themselves", and (his latest book) "Freedom of Mind: Helping Loved Ones Leave Controlling People, Cults and Beliefs"0, visiting his website www.freedomofmind.com, or watching his FREE videos on his website, do it now to help your husband to critically think for himself and not get drawn back to the WTBTS because of WTBTS induced phobias. The WTBTS's BITE control techniques are very powerful. If you do not have the time now, at least watch the following videos by Steve Hassan: Strategic Interactive Approach explained 2003 (1:23:23) and Roberto di Stefano, Ex Jehovah's Witness Elder interview - July 2013 (18:22).
If you do not feel comfortable planting seeds of doubts in your husband, at least plan fun outings with your husband so that he can meet more non-JWs who he shares common interests and encourage your children to make friends with non-JWs with parents who you share common interests.
Peace be with you and everyone, who you love,
Robert
