And within myself, I am still wondering, what could possibly lead a person back to gambling after successfully quitting initially? Know well the reason for initially quitting was addiction, does it make sense to go back to gambling and become even more addicted?
It is very possible to quit gambling and later get back to it while becoming even more addicted to it.
The thing is, I am very sure your friend isn't aware he is even more addicted to it. Such person cant stop gambling no matter how hard he tries to stop it.
Many gamblers have said this same thing in the past but all of a sudden they later came back to resume gambling and funny enough this time around was something else. However if you want to stop something for ever you need to mean it because coming back to it shows how weak the person is. Although it takes discipline to stop gambling mostly if it has to do addiction.
