Hello Honeybucket,
Thankyou for taking the time to share your situation. I know from experience that the limbo period is crap. You have my sympathy and understanding. It can be tough not knowing what to do, especially when you get shut down with every attempt, however small. I'm no expert, and can only speak from my personal experience, but I hope that any suggestions I make might be of some help.
There are actually some positives things that you have mentioned. One, you are able to speak with him about your doubts, and from what I read, he has not turned you into the elders. Two, he has said that he is okay with you not being a witness. This is excellent and you can use this to your advantage. These are indicators to me that there is a good level of respect and communication between you - maybe not in all things, but indeed in a general sense. I say keep talking. Not about JW things, but about everything else. Have fun, enjoy your marriage and the relationship you have. Never miss a chance to say how much you love him. Show him through your actions that your feelings toward him have not changed, just your feelings about JWs.
Some JWs (most in fact) are deep in the matrix. So deep that they simply cannot fathom any other way of life. It is synonymous with who they are. For them to admit that all is not well in the WT house, would open a pandoras box of family strife, loss of friends and a life turned on its head. This can be too much to even contemplate and so the protective walls go up, and everything gets blocked out.
It takes guts, but try and take things down a gear, enjoy being hubby and wife, and don't allow the situation to control you. Sometimes a change in circumstances, like you moving out of his mum's place can be the things that gets the spark going. The WTS likes to tell us that a change in circumstances can be the thing that brings a family member to the truth. This applies to those on the way out too! When the time is right, gently prod on something that is close to his heart. Instead of saying "This thing iswrong! JWs have been tricked!" I found the "Help me to understand this point" method more effective. Appeal instead of accuse.
Gently, gently does it.
It's not much, but I hope there might be something useful in there for you. We are here as a netowrk to support you, so never be afraid to ask for help.
Take care, and hang in there. We are all cheering for you.
