Thanks for the response, Pat. I'm sorry to hear that you are experiencing such a painful situation. I think there are some types of illness that can simply destroy a marriage, and indeed a person. I'm thankful to say that my husband has never experienced psychosis. This situation has really scarred him--both because he didn't realize he was losing control of his thoughts and thus his perception of our marriage/lives and because I did seriously consider leaving him. I think we both took too many things for granted, including that every bout with mental illness will seem somewhat similar to the last. I think we've both learned about being more perceptive, patient, and careful. We simply became too complacent with this illness and were very foolish to no have him in therapy. 

Looking back, the experimental exposure therapy we tried for him might not have been the greatest idea, and we should have a pdoc he liked in place already. . .
