Maybe you don’t know Islam. I’ve had the chance to know a wonderful woman (Italian-Swiss) and she married a non-practing muslim, and he became a Mormon (making also tha baptism) only to make her happy. After he comes back to islam and convinced to convert his wife. Beatings (also when she was pregnant) and bad words almost everyday. Islam give the right to the man to beat (it’s in the Quran, that I have and read it) you’re wife if he thinks that she are not so obedient, also teach that the mother have rights on its children only till they have 7y.o., after they’re a father properties. Many western man who marry devoted muslim women, must convert to islam also if they don’t believe in the religion beliefs because it’s a 100% patriarchal religion. So yes, you can cheat about your true religious beliefs very very well to obtain what you want. Islam and christianity have different beliefs about many things above all Jesus (holy books, and many other things) and it’s not absolutely negotiable deny (or put aside) the fulcrum of the Christian faith and celebrate (and say) words in which you proclaim that Muhammad is a God’s prophet and accept the islamic law.
You’re an atheist, so you don’t really understand that mixing two different faith, it’s not possible. There’s no compromise with God. Maybe you also don’t know how many male muslims kidnap their children and the mothers can’t make anything because they’re female and Christian. Read the book ‘Never without my daughter’. If a (devoted) muslim man marry a jew or a christian (he can), he MUST teach only Islam to the children. There aren’t 2nd options.
I hope that the original poster, will talk asap with a priest and a lawyer, and she must hide their passports so he’ll not have any chance to run away in Saudi Arabia. The divorce is always the last option but she must be very very careful and ‘study’ his behaviour. In the USA she’ll be protected and helped, outside NO.
ps: if there are errors, forgive me. My mother language is Italian…
