Glad to hear that your husband is out of the organisation. Even though it seems like a long time ago he can still find that the cult programming pops up when he leasts expects it to. He will also be more affected if he left because he felt he was unable to comply with the rules rather than leaving for doctrinal reasons. Reading books such as Crisis of Conscience can be immensely freeing since they expose the hypocrisy and corruption and it then becomes a much easier decision to leave doctrines and ideas behind.
We all find that from time to time we suddenly realise that the cult has affected us, whilst in it we do not grieve properly, we are more judgemental of others, we are suspicious of non JWs, we live under the constant pressure of not being good enough and we are socially awkward. Once out we have to develop our own personality without someone telling us what to think and how to act. As with any form of mental abuse we have to learn to to cope with it and move on with our lives it casts a long shadow especially if family members are still in.
The important thing is he is free and has been for a long time. I wish you both well feel free to ask any questions you need the answers to and we will try to help.
