I know that the number of women involved in gambling is very small because in some countries, people's views of female gamblers are still very bad and they are considered dirty and unfit to be a wife.
Personally, I don't see the reason why I should consider a woman who gambles
without her head as fit to be a wife. Woman are in-charge of running of homes and they are always in custody of the finances as its where they run their operations from.
A reasonable and responsible woman will definitely be considerate when gambling, if she has a passion for gambling and she will be moderate with her gambling budget as she will seperate it from the resources for home use.
But one without her senses wouldn't know the limit. Its a thing that has eaten deep down her fabrics, what is left of the control system in her..nothing.
The consequences to her family will be grieving as it will be repeated on a stead and that I can assure you, a man will not like to consider such a woman for a wife.
Your argument is valid since most of the time budget has been provided to women after the hard labor of his husband, if the wife will be engaged to gambling chances that she will endanger the family's finances, though it's not every time that female or women are just for that purpose as there are already women who also doing their own labor to meet their expenses.
There's always a consequence that depends on how each person is handling, in your situation for sure it will not be a good one for women to gamble for such a reason.
