I would say you have a leg ahead of many. You should count youself blessed if your husband thinks that way. Based on what I read from others, many would wish they were in your situation. Your priority right now should be not to push him further in. Loosen up a bit. He is on the fence. Think about it, if he is on the fence and you try to pull him your way and he decides to let go of your hand. In such struggle, he is guaranteed to fall to the other side. Keep showing him the kind of unconditional love that the elders would want you to give him if he was abusing you (although I could safely asume he is not). Keep asking question. If he questions your questioning, tell him that just like JEsus mentioned, you have to be like a child. The WTBTS would like to present that as being gulligle and manageable. I say there is on trade of children that the WTBTS willingly ignores... children question everything!! so why should you not!
The kids thing also bothered me a lot. More than the holidays, was the idea that they were being exposed to the doctrine without explanation. Then little by little I realized that I was understimating their IQ. Right now, if celebrations come up, I try to soften it by offering a better alternative. But I can see that the questions pop-up in their mind. Soon we will be taking a trip and will be spending about a month with a close relative who is not a JW and will be having a Christmas dinner, wether they like it or not. Family is ok with it. I am sure my relative will be having gifts for them. Nothing like such experience for them to see that there is nothing evil about Christmas. Wether they decide to celebreate it on their own or not, that is another story. I want the decision to be their own, not the GB.
