Yes it happens. He lost his wife slowly because of his addiction of playing gambling. Maybe he forgot his responsibility to his wife or maybe he lost all the money in gambling without thinking of how they would be able live without money.
it is literally bet his wife and it is not fair for the wife i just cant believe that even in this era that kind of a thing still exist i can say that we can possibly lost of wife not because we bet them physically but because of our addiction we will forget our obligation and they will go away and leave us.
