I am assuming you still believe in God. You have been given some great advice here, and I'd like to suggest something as well. Find a church that you like, ask to meet with the clergy there, and explain the situation as best as you can, including what your beliefs are now. Ask them to help you with perhaps some Bible study for your children to debunk the watchtower falsehoods? They should be able to guide you. You will get through this, but I'm so sorry for the heartache you are going through now.
Ruderedhead-- yes, I still do believe in God. I cannot accept that there is not a Creator. And I want to worship Him. The lies taught by the WTS have scared me to pieces, and I just don't know if I trust any organized religion. I do miss being a part of a spiritual community. I appreciate your suggestion, and it is one that I will most likely follow.
And, btw, my children have not been to a meeting in about a month. It turned out that he stopped taking them right after I wrote this post.
