Will you leave gambling if your future wife/husband tells you to do this ?
You need to be able to give up habits. And if you can't give up some occupation, and it takes away your strength and time - most likely you are dependent. Therefore, if a spouse asks to stop playing slots, for example, then if a Non-Problematic player re, he will easily refuse.
But sometimes there are cases when there is no addiction, gambling is given a small part of the time and money, which means it is a controlled activity, and it serves as an anti-stress and benefits. In this case, it would be foolish to refuse it.
You should be surprised of how religious and anti-gambling some people can be in certain communities in some specific countries. Here there are very evangelist communities which completely avoid alcohol and also anything related to randomness for the sake of amusement, does bot matter whether there is money involved or not.
So there is a chance one gets engaged with a person who has a lot in common with you but cannot accept you gamble, neither in a dedicated way or casually, because in their minds and due to the education they received, it would be matter of time for one to fall in financial ruin, which is not true for the most of the responsible gamblers out there who happen to be as well heads of their respective households.
