Well from what i have heard muslim men as well as woman they like the guy to be muslim this way they can tell them who they can marry. They might not allow it some go as far as picking the husband and wife for them this is done by the family so it might be they are keeping it from the parents.
Okay I know Muslims. Yes they want to pick out there spous but like every parent they want them to be happy. I know first hand that Muslims have strong felling for picking out who they want to marry there daughter or son. BUT it is also said that jews and Muslims dont get along. Thats a lie. So it all depends on how the parents fell about it.
