And to add:
Odessy1977 - You asked "Is this something normal in Morocco please? Please advise me." - This means your knowledge of Morocco is very limited. While I'm certainly not an expert, nor pretend to be, it's not wise to get married in a country that one has little to no knowledge about. That's recipe for disaster right there! You're already heading on the wrong path, and things will only get worse. You wouldn't enter yourself for an exam on a subject you don't know anything about. You would do your homework first. So why would you make a life-time commitment in a country you don't know about, without the required preparations? Which is why many of these mixed-marriages have a very high-rate of failure. The reason is simple...Fail to prepare, prepare to fail. I honestly believe if people did their research, they would think twice before they book that ticket! Google is your friend. It will provide you with a much needed eye-opening look into the usual outcome of these types of marriages. Afterwards, believe me, your reaction would be one of - "Oh God, what the hell was I thinking?! What was I getting myself into?". Followed by a sense of relief!
You're from London. Moroccans are living all over this city. Ladbroke Grove, Maida Vale, Paddington, Hammersmith, all over Westminster and other parts of this city. I'm sure you've came across them. Why would none of them marry you at first sight? But some of them living abroad will? Do you think the ones living abroad are any different? They are not! The truth is, a lot of people based in the West, go to 3rd world countries, to get married, due to it being easy, and they are 'accepted' rather quickly. But it's easy for a bloody reason! Which they don't seem to realize. They should put two and two together, and really know better. No excuse in this day & age with the information available online. A simple google search reveals all you need to know.
Another thing is, one of the many reasons for the abysmal record of these types of marriages, is the different expectations. Many don't realize that they will be sponsoring their partner AND the family. It causes a lot of problems down the line. As they are expected to fulfill the many, and continuous (generally money) requests, from their partner and the family. This is not what they expected would happen. But it usually does. You're not only marrying them, but the family. As I said, fail to prepare, prepare to fail. You need to do your homework, ask yourself whether it's worth the risks, before embarking on such a life-changing experience.
