It didn't happen to me or my own family...
Often have heard how many cases where husbands spend more money on gambling until they don't have any money, the reaction as a wife acts where they want to ask for a divorce because of injustice to their family, then this is more trouble until it ends up being separated without apologizing.
That gambling often destroys a harmonious couple if you as a man do not maintain the balance of money spent on gambling, for gambling itself never put a lot of money quite a bit even 2% is enough, well sometimes human nature will not be satisfied with a little gambling allocation.
There are several things which could perturbate the harmony of a couple, there are several things besides gambling. It could be alcohol, abuse (physical or psychological), lack of honesty or even an affair.
Though, one should never underestimate the impact uncontrolled gambling can have on the integrity of a couple. There have been cases about couples separating over money management, that is true, and it would be up to them to face the actions of one of them gambling away money or to separate from each other indefinitely.
It is easy to assume smthose kinds of reckless actions can be forgiven, but it is not that easy, one needs to put oneself in the shoes of a woman who just discovered all their money being flushed away down the toilet. I would not blame anyone for separating because of it. It is very though.
