superwoman, i didn't read all the posts, but i really need to say this: r u really qatari? i'm sure you are, do u live here? do u know about all kind of secret relations that lead to marriage most of the time? how about dating in cars or in hotels or in cinemas?
i think traditional marriage is overrated by yourself here, i think only very few families are still following this by the book, yet most of the guys and girls are having phone and car relations for years before getting married.

finally, don't worry, you really won't get married this way because i'm sure you'll find your soul mate somehow and get to know him well before a "fake" khatba come to your house and ask you to marry him.
Yalla!
