Thank you everyone for the replies. I've been upset all day about this, so to get home and read this all now is comforting...a bit.
I will say, I am an opinionated, tough east coast girl that had a pretty major career back home. He likes that I am so independent, have a voice and am not a pushover. All that being said, I'm a good wife and am always thinking of his needs. I think he knows better than to try to strong arm me and pull the "head of house" card. He really isn't like that, haven't seen any inkling in 4 years and I pray that he never shows me that side of himself. I would never have moved across the country for anyone that wasn't 100% good to me.
We have planned to not have kids, which I know would be a major challenge as to how they would be raised. I find it interesting but very, very sad how much I've read on this site about JW's and pedophelia. There are molesters in his family, and its a major reason he doesn't want to have kids.
He doesn't leave watchtowers around, in fact I've never seen one in the apartment. He has his bible on a kindle, so that was a good point by The Fall Guy, but sadly, its lost on this argument. I do always iron his clothes for him when he goes to his meetings. He just got accepted back in, and I was happy for him because I know it meant a lot to him and his family. I'm sure deep down they all hope I'll convert someday, but I'm never joining their cult. I've made it very clear and they seem to be ok with it.
I hope I can reason with him and cite some of the things I've read here in the comments. He is very quick to talk about pagan symbolism and Christian holidays, so I'm sure thats where the argument is heading. To me, my tree is family history, tradition, winter, beauty, art and nostalgia. I'm happy to remove any Santas or religious ornaments (or at least put them on the back of the tree!) if that's what he wants. He mentioned just decorating for winter, but the tree is the only thing I want. I don't care about other decorations. I'm happy to call it a "winter tree" or a "nostalgia tree" if that will make this go smoothly.
He said he never had a problem with my tree when I lived on my own because it wasn't "his house". He would come and stay with me 3 days a week at my apartment until I moved out here in august. If there's no compromise and I'm forbidden to put the tree up, well, that's unfortunately where our marriage will start to crack. I can't be expected to give up everything...
I will report back after we talk. Thanks again for your insight :)
