Im confused by the religious aspect of this situation. Im not religious but it does sound like you do need to seek some spiritual advise from your church to help you better understand the aspects of the bible that are keeping you in this relationship.
How do you feel DH will take to counseling? From your post he doesn't sound very supportive so I wonder how much luck you will have getting him to attend?
I would also focus on a smaller time frame. A year is a long time to foruc on counseling. I would look at a 2 or 3 month period of getting him to attend at least once or twice a week. If at the end of that 3 months he isn't attending then I would walk. If he is, great, readjust your time frame & goals.
Good luck! I think you will need it
