Hi, Natt. I'm brand new here, but I'm not new to seeing really big problems in churches. I think you should let the pastor know you will not tolerate the revealing of your confidences. Here in the U.S. such a thing is against the law. I would not at all recommend that you tell anyone of your history in order to beat him to it. If you give the information out, then you would have no legal recourse. If he gives it out, then you do. If you are firm with him about it, he will probably back off. In this situation it would not be wrong to consult an attorney. You wouldn't have to tell the attorney what the confidences were. It would be enough for him or her to know you are being threatened. Your pastor's behavior is 100% unethical and very cruel.
