SJ, I didn't watch it but anyways - the husband saying that he would leave about the hijab. If I took mine off my husband wouldn't leave me. I'm not sure how not wearing the hijab would be making the husband sin and TBH I think that threatening to leave if she doesn't wear the hijab is a bit off. Men who seek to control their partners via threats and blackmail are icky in any culture.

Lots of Muslims would prefer the term assisted marriage over arranged marriage. Arranged marriage kind of brings to mind the European tradition of arranged marriages between royal and 'noble' families where a girl is betrothed by the time she could walk and shipped off while she is pretty much still a child to marry a stranger. A Muslim assisted marriage is rather differant. I went to school with a Morman girl who went to the US to marry a guy she had never met in an arranged marriage a month after she finished year 12. I was really shocked and I questioned her at great length lol but she seemed really happy about it and from the reports that filtered back via her sister (who went to uni instead) she was happy in her marriage. From then on I was always fairly accepting of arranged marriages if both partners were happy to go down that path. Statistically they are just as likely to suceed as any other marriage.
Most Muslims meet their partners via the same channels as most other Australians. They are introduced by family and freinds or they meet at work or uni or community events. I know one couple who met on a forum. Many arranged marriages are between a couple who know each other well and have asked their families to arrange their marriage. The arranging is often more to do with the details of the pre-nup. A Muslim marriage is not valid without a mahr (a sum of money paid to the bride which remains her property - this is insurance so that if she becomes a single mum etc she has some one) and a marriage contract/pre-nup which can contain pretty much whatever you want and can be incredibly detailed if you wish. Most importantly it covers things like alimony and child-support. Generally a couple will get their families to negotiate this (although they might direct the family) so that they are not tempted to give up their rights because of affection/young love.
Also in Islam sex before marraige is considered a sin so an assited marriage often just means that the familes will visit each other a lot so that everyone gets a chance to get to know each other without temptation.
I guess that one of the key differances is that when a guy shows up you know straight out that he is wanting to get married - there is no danger of dating a guy for a few years only to find that he doesn't want to commit/have a family.
In some cultures a couple will get married but not move in together for several months - this gives them a chance to get to know each other a bit better and go away for dirty weekends if they want but they can still back out without the hassle of splitting property etc.
