Umhamad ask this question in islam online. You can get an answer from one of the Imams.. or better yet take yourself on down to the ministry of Awqaf,Qatar guest center or Fanar. If you dont want to go down there give them a call, Q-tel can give you the number for both.

Reality is there isnt much you can do, he is supposed to consult you out of courtesy but sadly enough it doesnt happen. If you divorce him you give up the rights to your divorce money and depending on the age and sex of your children you may also not keep custody of them. A lot of women in this situation wait until they go on holiday to their countries and stay with their parents to keep the kids. You may not hold onto them for long but it is worth a try.

The reasoning behind multiple wives was to ensure that war widows, divorced women etc had someone to take care of them. This was practical in the time of the prophet when war widows were left stranded as women really didnt have the ability to earn a living like we do today.

Islam permits up to 4 wives if you can be fair to them all equally, but if I am correct ot also says in the Quran that you cannot be fair... you can interpret this as you like but I think it is pretty obvious. Polygamy is not encouraged but I think people can use this to their advantage, which I think is abusing it a bit.
