Well, I find this very difficult to resolve. We cannot force a person to quit gambling. While we are gambling. If economic conditions are good and both people know how to control themselves in gambling and have a lot of free time. Both could use some time to gamble. If either of the people has an addiction and a difficult economic situation, I think both should quit gambling. We cannot gamble in front of people who are addicted to gambling, and they will not be able to go through rehab.
Let them determine their own path in life, meaning whether they are good or bad at gambling, they are the ones who judge and if a husband and wife enter the world of gambling and they enjoy it and it doesn't even become a burden on their family then what's wrong with them gambling?? And it must always be remembered that husband and wife as gamblers must cover up this behavior as much as possible in front of their children so that their children do not follow in their parents' footsteps.
However, gambling is a bad behavior in life and not everyone can control themselves well when gambling.
If a husband and wife are already gambling, enjoy it together and maintain good control and always be careful in every gambling game they play.
If we are referring to the sense of care between people then yes maybe I would also say the same thing as you in the sense of allowing them to continue gambling and without giving any best advice, but don't we have a humane sense, if we realize that in fact the whole activity is not recommended then why don't we give them a little advice and understanding that is straight and true? Honestly, I can't help but care about everyone whether it's my friends, relatives or even strangers, especially if they are married, which means they have full responsibility for the finances in their family, especially in terms of balancing so that everything can remain fine.
Sometimes people who have a goal to have fun are very likely to enter the addiction phase unconsciously and experience problems with their finances, well even if the couple considers gambling as entertainment but still the risks are always unavoidable and one of them is like what I said that it is possible that over time they end up with addiction, you have also said that not everyone can control themselves and emotions in gambling, isn't that also very likely to be experienced by this couple and then they experience problems with family finances? It's basically everyone's right, but certainly hopefully they can change their point of view to be more realistic so that they can consider anything correctly.
