What is the point me telling lies just to cover up my gambling track if being asked about such and besides it is my right to do whatever I feel is okay with me to multiply my source of income. So telling one a lie about your gambling loss just to cover up wouldn't help matters because you never can tell if the person could be the one to help you get back on your feet through advise or even teach you more gambling techniques that could be of help to you.
There are different relationships in couples, and often we can see, When the man is not the head of the family, and he does not even have a job. And the woman in the family is the main source of income and she gives money to the man, and therefore he must report on his expenses to her. Either directly or indirectly and, of course, if such a woman sees that the money begins to disappear into nowhere, then she will have questions.
If this guy is a loser gambler or a loser bettor, then he will not be able to explain why the money disappeared, he will have to lie.
