Someone who is addicted to gambling will find it difficult to recover, and to recover they must have awareness, while for people who are addicted they tend not to think twice before gambling, they will only think about winning which makes them not consider the actions they will take even though it is high risk. With people who are addicted to gambling, in my opinion they have the wrong initial intention where they think that they will be able to win easily while the reality is not like that. Advising him to reduce gambling activities is a must, especially if it is a close relative, but have you ever experienced where you are annoyed because you have often advised him but there is no change in the addict? I have experienced this and what I did in the end was to let him be until he was really miserable and regretted all his careless actions
That's the problem because they think they can make money easily in gambling so they don't think long before starting it and addiction like this will be increasingly difficult to cure if not controlled properly. Some people who are not addicted set aside a special budget for gambling and stop when the money runs out, this way of gambling is not a problem because people will find it much easier to control themselves when involved in gambling.
I have also experienced the same thing as you and after we advised them, they did not change but got worse and even said that if we also gamble, why advise them. But they do not understand that the gambling we run is more responsible and not excessively involved like him.
