Sadly, some people may never be able to recover from gambling but even though this might be the situation it's possible to manage through different ways and one of them is by staking low amounts and money, this can help you reduce the losses that you incur overtime. Another thing is to reduce the time that you spend gambling, the more time you spend gambling the more more money you end up losing
It all starts with a small wager and until the accumulated losses become big. That's when a returning gambler will also become addicted again. The success of quitting will be wasted if that gambler can't help himself but to gamble again. And that's the reason why he's not going to recover anymore, because his mind is already stuck in gambling again. Maybe having several problems pushed him to his limits again and that's why he's back. We don't know and we will never know the actual reason why he did that again. We can only wait for the confession and validation why he's back to gambling.
