Gambling addicts do the darndest things. This man in the story must have successfully kept his addiction a secret from his wife and family. Or even if he didn't, they must have downplayed the severity of the addiction. As it has been said over and again, addiction exists and thrives in secrecy. That's its superpower but once exposed or talked about its potency is reduced. It is not enough to say gamble responsibly but to reach and guide them how to gamble responsibly.
This is true, it looks like he had kept his gambling activities as secrecy from his wife and family. Many used to gamble together, when the gambling activity is on the losing streak the family members used to take decision to stop gambling. By the time husbands used to suffer as they can't control their habit. This is where they try to keep it as a secret and when they weren't able to manage the loss ends up with such bad behaviour. As said rather than saying gamble responsibly it is good to teach them how to gamble responsibly.
Well, for some people, sometimes it is difficult to maintain control of what they do, in bets when a person does not have confidence in himself and is carried away by adrenaline, he can lose all his money and enter the casino with a lot of money and go bankrupt if you want, so that is what you have to avoid, especially those who have family, children, because you have to be responsible with them first before anything else, then if you are a person who has duties, you must comply Overall, because that's what he has his people for, he can't stop doing it because it would be something very bad, so yes, responsible gambling comes in here.
