Isnt there any other local church fellowship you can be oart of. Just go there and mention you now belong there. If they want to make a big fuss about dismissing you just say they dont need to do that, that your time there is up and its a new season for you and your husband and God wants you to go elsewhere. They seem to me just being bureaucratic and petty about it. The bible does say dont hang round those that have a different doctrine or teach a false gospel dont even say to them Godspeed.
