Cross cultural: Relationship and marriages are tough enough, even when both parties have a common race and culture. However, if they are both from divers’ cultural background, languages, orientation, opinion and beliefs, these may be harder knots to crack. These are lines of divides, some of the major challenges of relationship and marital problems, without mentioning other difficulties and complexities.
I have always advised on a more serious note, for couples to agree on most of these issue should they desire a smooth relationship or marriage. But they cannot settle this fundamental issues, then they need not proceed, except they are just adventurous people who like to explore. Therefore in the past I have preferred people to marry people of their own cultural background, language, perception or orientation.
