he is talking to me as little as possible and says "I have changed the rules'. wow, people change and grow in a marriage.The rules do change.
The rules do change, people change, and circumstances change. That's part of life.
However, I do have compassion for your husband. I do NOT condone his treatment of you, but I can understand how a shift in such a fundamental belief could greatly effect a marriage. To have a spouse reject that something that is such a large part of their lives, no matter how "good" the decision is, must be very difficult. I saw the identical (but flip-flopped) situation happen when my Aunt embraced witness theology after being married for nearly 20 years. Her husband felt exactly the same way--the rules had changed and my uncle suddenly didn't know how to handle this woman and her new beliefs.
I believe there are three "deal-breakers" when it comes to marriage: Handling of money, the desire to have/how to raise children, and religion. No matter what the views are, coming to a common decision about these issues is essential in whether a marriage can/will work. And when one partner dramatically changes their view of any of the big three issues, it can be terribly stressful for the other spouse. I have seen it happen with financial decisions and handling, I have seen it happen several times with couples who initially agreed not to have children where one spouse now desperately wants them, and I have absolutely seen it happen when religious beliefs change dramatically.
That said, the difficulty experienced does not mean that a marriage should be dissolved. I believe the vows taken at your wedding are binding, and that the most difficult of situations need to be dealt with. But it isn't easy, it can take a lot of time and hard work. The fact that your husband is willing to read COC is very encouraging, he must love you very much--I have heard so many stories relaying how spouses wouldn't agree to ANYTHING they deemed "forbidden". My wish is that you will be kind to each other during this difficult period, and come out of this period with a greater understanding of each other, having made united decisions that will ultimately make your marriage stronger. I will be thinking about you.
