All of that really wouldn't be a problem if your wife/husband basically had a formula for maintaining a balance to prevent unwanted things or situations, but for the most part, they can't do it, it's easier said than done and that's a fact. It is gambling that ultimately is likely to make a person experience rapid changes in many aspects, whether it is in terms of the allocation of money at stake or also in terms of changes in behavior and traits.
Even if you treat gambling reasonably and gamble in moderation at first, there is always the possibility of increasing interest, many people who enter this phase of change end up betting something that is far from "reasonable" or "unreasonable", And of course this is a situation that can interfere with your relationship with your partner in a family where the main problem will be in terms of "money", losing balance in terms of money especially caused by really bad habits such as gambling of course it can trigger new problems such as divorce, so I think this is a problem that is very possible.
That's right, sooner or later the habit of gambling can change a person character due to a simple factor, namely addiction. I think that even though financial balance in a household can be fulfilled, it is not enough to make a family relationship run harmoniously. What I mean by this is that gambling apart from spending money also takes up time, which should be spent with husband/wife and children, this will not happen. So avoiding gambling activities if you are married is indeed better, in order to maintain a peaceful household integrity.
We rarely see a wife experiencing an addiction to gambling, in most cases it is dominated by men. Even if there are maybe only a few women, but if these women have children then it is very fatal, because it will affect their interactions with children directly or indirectly. Therefore, I think it is better for husbands/wives who have a gambling habit to stop, because family values and goals can be lost due to this bad habit.
