I have never met an addict who told me about his gambling habits. Maybe if someone really told me about his addiction, maybe I would try to advise him not to judge and try to help him as much as I can and advise him to go to a professional place that can cure his addiction if with professional help, the addiction can be overcome quickly, especially if he has the determination to recover and wants to stop gambling.
Advising them is a sure way to do it, of course giving good direction so that they can be aware and reduce their gambling or even stop completely, but it feels almost impossible because once they are addicted they won't be able to stop easily, of course they need a difficult process. to be able to stop gambling completely. However, everyone who receives someone who tells them about their gambling will certainly advise them, but if they continue to encourage them, maybe it is only done by friends who like to joke, but of course advice like that is not the right one. because it helps him to recover from his addiction, that's true.
When someone approaches you and tells you about gambling, you have to be careful because the person could end up borrowing money, perhaps with the aim of gambling again. and if that happens, it's best not to lend them money because it's the same as giving them a way to continue their addiction which is leading them to the destruction of their lives.
