Many people keep gambling a secret and many do not like to keep it a secret, but those who lose regularly in gambling have more problems in their families. And the gambler admits it only when he is able to win repeatedly in gambling, but it is not possible to win in gambling always, sometimes he has to lose.
But the problems start when the gambler loses more money than he should lose, then the problems arise in the family. And due to the creation of problems, later separation can occur between the two, but I have seen such problems in the family of gamblers in marital situations.
Some people doesn't keep their gambling habits secret but yet they still lose so much money and face gambling issues that leads to some family issues. You can remember the incident of some addicted gambling partners that stole from their wife or girlfriend just to continue gambling, while some stole their kids school fee and went to gamble with the money. But the worst of it is when you get married to a partner that doesn't like your gambling lifestyle and you then have to keep it a secret, meaning that any day she finds out, the marriage is over.
