This is a fascinating scenario that raises many concerns concerning how gambling affects family dynamics. The "gambler's fallacy," which holds that one huge victory will solve all of their problems, is obviously rooted in both couples. However, in actuality, they're probably just incurring more debt.
The best course of action would be for both partners to stop gambling and get assistance. Still, it's not always possible for both partners to leave at the same time, and it's easier said than done. Then, it could make sense for the partner who is more deeply to quit, then help the other one to quite as well.
I am in favor of both partners stopping gambling and getting help. But maybe it won't be easy for either of them. Moreover, both of them or their husband or wife still return to gambling. They really have to see how much they want to gamble. If they both still have the urge to gamble, they should be careful because it could be a sign that they are starting to get addicted to gambling.
They should try to suppress the feeling of wanting to gamble. They must be able to reduce their gambling activities before it makes them gamble more often. Moreover, we know and many people already know that gambling can really make them addicted to gambling. I think people should be able to find ways to avoid or reduce their gambling activities.
If one of them is already gambling, they should start to realize that it can cause them problems that they will not realize. And if his partner finds out, he can start to make them aware and show them the impact gambling can have on their lives. But they should be able to realize that gambling can cause problems for them.
