People who gamble secretly without their partner's knowledge usually won't be honest about the income they get from their work or other things. Because usually some people who are married need their finances to be known by their partners (women), if he is honest about using his money for gambling, his partner will most likely not allow it; therefore, many men gamble secretly without their wives' knowledge. However, some of them also become addicted to gambling so they become irresponsible and even reduce the nominal amount of money that should be given to their wives in full but use a lot of it for gambling. This can certainly cause arguments and even end in divorce.
