As a Mormon bisexual man I live in the "other circumstances" mentioned in The Family: A Proclamation to the World where "Death, disability or other circumstances may necessitate individual adaptation."
Thanks to Into the West I watched an excellent episode of House last night. It deals with the wedding of a young couple. She is straight. He is dealing with SSA from which he says he is "cured." The episode helped me understand the sense of betrayal my wife felt when I finally came out to her after coming out to myself many years into our marriage. The ideal that child should be raised by a committed mother and father is also something I've pondered since watching the episode. A mixed orientation marriage is not only difficult for the wife and husband, but it also has implications for the children that may be brought into the union. True, no marriage is perfect, and I don't know if there is any data on the effects of MOM relationships on children in those families. If you are aware of any information on this, please let me know.
