TBH, I don't give a damn when it comes to sharing with people about my gambling habits but I only do that with my friends as I know I can trust them that they won't speak about the same to others even if we fight with each other some day. However, keeping your gambling habits a secret has nothing to do with not having proud on what we are doing because you are respecting your rules towards privacy and you're not breaking it by not saying anything about your gambling habits to anyone, which is also a good thing to do.
Gambling habit is something we need to keep to ourselves or else we might hurt people that are around us especially those that care about us. There are some persons that don't like it when they hear that there love ones do gamble for a living. It might look like a taboo but there is nothing we can do about. Gambling is not supposed to make us do things that are not ethical just like some people do anything to make money in the society. We need to watch ourselves and make the right decisions so that we are not going to go astray. Exactly, better decision making and avoiding things that may harmed not just us but more on the side where people around us is also needed to be considered, being engage into gambling is not an easy task to stop, there are people who got addicted and have that big problem which includes their relationship with their close friends and love ones, something that we really don't want to happen to us, we can avoid things if we wisely choose our decision not to engage that deep with gambling.
As long as we don't ignore our daily obligations, especially if we are family members or the breadwinner, I do not see anything wrong with hiding our love of gaming. Because some people don't want others to know that they gamble because it's their job.
It's also possible that they're keeping it a secret because they don't want to ruin their family or cause another argument with their husband; either scenario is possible. There are thus several explanations for why it is kept a secret.
And at that time his wife began to find out that he was a gambler, even though he was trying to cover up his gambling to his wife, over time he would definitely be found out, because one day he lost, there would definitely be a fight in his family.
You can't cover anything if you already using money that allocated to something important, that kind of gesture only proves that addiction is already present, since you can't control yourself and you are already willing to use money that should be used to a much important thing compared using it with your gambling activities.
As I am the one who push the idea that gambling habit should not be kept as a secret 
As there is nothing special about it, whether it is just a hobby, a way to spend time or have fun. I also find it absurd to hide it from someone, as there is nothing to be ashamed of, this is legal, this isnt bad thing to do.
