OOmpa, I'm not on the board often, so I don't know much about your situation. It surprises me that your therapist would be suggesting divorce (however subtle the suggestion). A good therapist will try to help you find your way and try to help you clarify your thinking, but you are the one who chooses the direction. That being said, perhaps you are giving off some strong signals that you feel divorce is inevitable and your therapist is simply reflecting your feelings back to you.
I hear what you are saying about not having much in common outside JW, and I'm sure you would face a difficult road if you try to keep going to meetings for the sake of your family. At the same time, divorce is extremely traumatic, particularly on the children. I'm twice divorced and would never remarry, but I do wish I could have found a different way to do it.
I think your therapist has given you good advice overall on slowing down and finding stability - its hard to make good decisions when too many things are competing in your mind.
I've found that taking a step back from things and asking a couple key questions has been very helpful: 1. will this matter 10 years from now? 2. how do I envision my future and where do I want my life to be 10 years from now? Another important thought I've come to embrace is that I cannot change the past so there is nothing to be gained by agonizing over past choices and past behaviours I regret.
Seeing a good therapist can make all the difference, so I'm glad you've found someone who you are comfortable working with and who understands a bit about your background as a JW. As we all know, that's an area many of us have a problem with.
