According to the Guardian article on the judgement, Princess Haya was religiously divorced without her knowledge, one of the things that made her grab her children and run when she found out. That's why she had her children made wards of court in England. She also apparently saw one of the imprisoned stepdaughters just before she left. I suspect she didn't go home to Jordan in order not to become a political football between the two countries. It seems that her ex underestimated her; with a father, brother, two sisters, nephew and niece all passing out of Sandhurst, and a sister in Special Forces, she was never going to be unresourceful if she was anything like the rest of her family.
Dubai is tacky and treats foreign workers like slaves. I grew up in the Gulf and wouldn't go near it any more. Try Oman (Muscat).
