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.
