Does this worth telling him or not please i need you collective ideas.
Don't hide things from your hundred or loves ones, something as serious as gambling need to be told to your husband so he doesn't get angry when he finds out that you have been gambling with money that could have used for other things in the house. Regardless of it being your money that you're using to gamble and not the family money, you still have to tell him so it doesn't spoil your marriage. Gambling has spoiled alot of families, If you love him tell him on time.
If he finds out he'll think you're hiding other things from him and he'll never see you the same again to trust you so don't hide anything from your husband. If you're scared that he'll ask you to stop gambling, take your history of gambling to him so he can see that you're not just losing money but making some profits while you enjoy yourself and also make him to know that gambling won't interfere between your duties as a wife.
