To me that actions shows that the addict is still very responsible and knows what he is doing, but just that, he can't control his gambling urge, so at that, we don't need to generalized things, since we already know that every individual have they own difference's and ways of doing things.
Others are just putting too much negative to the term "addicted". Not all addicted are considered on the verge now of becoming crazy. I truly believe that there are lots of addicted gamblers that are responsible on other aspects of their life. They just do gambling maybe because of personal reasons and seems these addicted gamblers can afford to cover their gambling expenses without affecting their finance on their family.
If only all addicted gamblers are like that then we might see a healthy gambling environment but that's not possible to happened at everyone.
Of course, there are so many stages of addiction. But if you already recognize that you are on the verge of it, better alter your lifestyle.
If you are still clearly thinking about what's going on with your life, it may not be too difficult for you to change the path you are traversing with.
Don't get too deep before you wake up your mind because that would really be a challenge not only for you, but for your immediate family.
