I don't know why someone would be hiding something like gambling from their close people. As far as I'm not collecting money from them to gamble, why should I be afraid? In fact, telling your people about your involvement in gambling can even help someone avoid becoming addicted, because it's possible they could be monitoring such person is spending. This way, the person's rate of gambling might reduce.
In fact, what may have caused the lady to break up with the man might not even be because he's a gambler, but because he didn't tell her about it from the beginning. And truly, that kind of person should not be trusted. A person like that, can even be doing something worse than gambling, might still be hiding it.
As long as someone is very close to you, especially your partner, it’s not good to hide certain habits from them. If someone is hiding something, it may mean that thing is doing is not ready to leave that particularhabits forever.the truth is bad things everyone love to hide nobody will like to hide good things so that means gambling is bad thing to him.
