I would say after 28 years of a "cross cultural" marriage there simply is no spiritual harmony. It has for me, been like being in a marriage by myself. With loving respect I would counsel anyone contemplating this sort of union to consider strongly 2 Corinthians 6:14.
That being said, I believe for those of us who did not heed God's guidelines, should stay in our marriage and believe God to display His mighty work (Romans 8:28).
