And same goes for the woman whose husband is an addicted gambler, she may likely try to see how her husband can come out from the addiction but if all her efforts proves abortive, I will not blame her if she packs up and leaves the marriage.
It is very important for all who gamble to gamble responsibly and avoid getting addicted at all cost.
Maybe husband should also consider leaving his wife because when they get married, they must have given each other vows to be together when they are rich and poor, when they have joy and problems. Now wife wants to observe how husband try to solve addiction problem instead of helping. Love joined them, but money separated them. From my point of view this wasnt a real marriage then. I would leave a partner if money is what only matters to her.
