The problem came when he said he could not marry a woman who was not a Muslim and that he wanted to go back to Morocco to be near his family/parents, and she found as nice as he treated her and as much as she genuinely loved him as an individual, she still could not convert and move to his country and live as his wife, and she cried about it for easily a year.
That's a story of really falling in love, I think, and still not being able to handle the culture shock. My sister on the other hand, I think her ex-husband was a brute who was connected with terrorist-sympathizers, and she committed the mistake of marrying a man she found sexually attractive without getting to know him first, because she romanticized his background.
My sister is still very attracted to Arabic men, though. I just hope if she gets involved again, it will be with a more Americanized man of Arabic descent who she loves as an individual, and not for romantic ideas about his culture. I don't think that will be a problem after the shock of what she experienced with her ex husband.
I know being attracted to particular races or cultures seems pathetic to some people, like I concerned myself for a time asking myself if I was attracted to xyz individual BECAUSE he was Russian, and the answer was quickly no when I met other men from the former USSR who I found physically unappealing or appalling in personality, I was reassured that although I like a certain culture, I'm still attracted to individuals, not their race.
Because that is not a good reason to be with someone, like my sister's brief young marriage, or like men who sexually fetishize far East Asian women and then are shocked when she's Americanized and not a fantasy love slave.
