the limbo stage

I know I haven't been to this site for several months, but having been lulled into a sense of "everything is going well, why rock the boat," I find myself in a sort of questioning limbo. Since coming back up to The Slope, I have found a husband that is kind, patient, and happy. I know that I have felt that before, but never for this long. Before any of you talk to me about hope, change, and moving forward, let me tell you that I have only been with him this time since Dec. 20 - 2012, and we were apart for almost five months before that. I knew that there would be a "honeymoon" stage of being kind and careful, but that has never lasted for more than a couple weeks. Given the fact that he has never really admitted, or believed, that he has an addiction, and has gone through all the motions of repentance, but never taking the bishop's counsel to confide in me "when" he slips (not if), and went to the 12 step program to take notes on what all the other men were sharing so he could tell me that it really does help him to know that at least he was never like that.... there is a nagging feeling that perhaps the hard part isn't behind us yet. I have prayed and received answers time after time for everything from "Is he still involved in pornography?" to "Should I go back up to the village to be with him?" Well... I am here. I am confident that The Lord wants me here. I am happier than I have been in years (he's had this problem long before our marriage, and we've been married 39 years), so why do I have this feeling that the floor could fall out from under me at any moment? Do I lack faith? Am I deceiving myself? ... and have any of you been in this limbo stage before?
