Hindi serial wives and their devotion to their husbands

One fact has always puzzled me about the way that Hindi serials present the devoted wife. She is the one who will do what she can do to protect her husband and his family, will suffer all kinds of indignities and torture, but will keep on struggling until she manages to make things right. Sometimes it may take years, but she will do thing right, for example, you have Tulsi of Kyunki Saas Bhi Kabhi Bahu Thi, Parvati of Ghar Ghar KI Kahani, Kumkum, Praachi of Kayamath, Saloni of Saath Phere, the list is endless.
This is epitomized as the ideal of what the Indian woman should be like. In addition to the fact that this is a highly regressive image that many men would expect their wives to be like; there is another big flaw in this whole concept. If the wife is shown to be devoted and ready to sacrifice all, somehow she is ending up not telling her husband the truth. Implicit in this argument about saving the family and the situation is the fact that they don't tell the husband about the whole situation and end up in a case where the husband may in fact not believe them.
Also not telling the husband could be implied that either they do not consider the husband as being able to help out, or not able to handle the situation, or even otherwise not believe her. A mighty amount of trust they show towards their husbands.
