I lived in Manhattan for forty years and witnesses many Jewish/Christian couples. Past generations one usually converted to the other's religion. My generation seems different. People respect the other's backkground without trashing their own. I worshipped in large, urban churches. When Christmas and Easter arrived, many Jewish spouses visited the church to spend the impt holidays with their spouse. Some went their own way to church or synoggue but it did not seem to mar the marriage. Well, these were secular or reform Jews. Perhaps a few conservative. No Orthodox Jews. I suppose this was possible b/c neither side preached supremacy.
I wonder how any marriage stays together when only one becomes a Witness. It affects private marital affairs. The religion is so encompassing it affects life in general. It is not just one segment of life.
I am active in Adult Children of Alcoholics and Dysfunctional Families. My family put the D in dysfunctional. The central tenet of AA and other Twelve Step programs is that you focus on yourself. It is not possible to control another person. If lawyers could solicit, I'd attend a KH and hand out business cards for divorce law. I recall the grief of the sisters concerning their husbands. Do you look forward to Armageddon when your beloved will die horribly? When people preach to me about anything, I shut them out with locks on my mind. Rather than converting me to their viewpoint, they make my initial view strong as steel. Example is another matter. True discussion is another.
I see marriage as special. Society certainly regards it as so. All sorts of tax breaks (unfair), rights, privileges and confidentialty attach. I don't know how spouses stay together.
