Gambling and marriage are different things, sometimes gamblers hide their gambling from their wives, I think if he is addicted to it then there is no reason to hide it. Gambling puts a lot of pressure on the family, so before marriage there are many families who do not want to marry a girl who gambles. Yes, I saw a friend of mine who gambled but the girl's family did not know about it, the marriage was fixed but when they found out that his son was gambling, the marriage got divorced. If he gambles, then after getting addicted to it, he does not take care of his wife properly, but gambles with the money saved in the house. I think gambling can be done but not excessively which causes problems between husband and wife.
