Lies like that in the first post here in the thread are not hurting ones,they don't do any harm,quite the opposite they give the woman what she wants to hear from her husband and the husband can keep to himself that he loves gambling more than her at certain times.The only harm I see in such declarations is exactly the signs of addiction I see in here,if they truly care about gambling more than anything else then this is a big problem which they need to fix as it will undoubtedly hunt them after some time have passed,the wife will find out and that is how a big number of divorces happen,the biggest number in the country where I live is exactly from gambling.
Every gambler will definitely lie to cover up what he is doing with his gambling activities to the people around him, including family members.
Likewise, husband will definitely hide his gambling activities from his wife because he doesn't want it to become problem if the wife finds out that her husband is gambler because the wife will have different sentiments when she finds out that her husband uses some money to gamble.
Moreover, not everyone will accept or consider gambling activities to be good activities and most people have bad view of gambling.
But in my opinion, the only person we can prevent from knowing about the gambling activities we do is our children, as father I really don't want my children to know that I often gamble.
This will have much worse impact than the wife finding out, if the wife finds out it might just be angry but if it is child then it has the potential to make the child curious and want to know about trying gambling.
