As you said about risky activities in gambling it is actually not that risky if you can limit yourself. Limiting means playing within your financial capacity and not gambling beyond your financial capacity. The most effective method is to gamble according to your bankroll every week. Limit the time you spend playing and managing your bankroll in line with income. Addiction will have a negative impact on family life in many cases divorce is also observed. Therefore, not only gambling addiction but any addiction can have a negative impact on your family life.
Well, that's true. Gambling is basically just a form of entertainment, and if done in moderation, like anything else, without overdoing it, it's not risky or problematic. However, many people, especially those in the lower middle class, take gambling too seriously because they think winning is easy and will help them change their lives little by little, or perhaps drastically. I agree with you, any addiction can have negative consequences.
If anyone is just taking gambling as a form of entertainment and is being responsible in gambling, it is not supposed to lead to divorce, except a situation where the person is now addicted and the situation became unbearable and if one is even a responsible gambler, there's no reason you should not even tell your partner that you enjoy gambling for fun.
