Yes it is true. Addicted gambler won’t listen and won’t take advices because what they usually do is to justify their mistakes and satisfy themselves with their vices. They are like so genius that they have answers in everything that we want them to see negatively. And even if they are going to lose everything they have even their loveones, it is not enough reason for them to quit. It will always be depend on themselves to realize how bad it is to make them quit.
Yes it must come to there mind then only they can listen our advises or else they don't care for our suggestions. when they will realise that they are losing money and loved once that time they only ask suggestions. I think addicted gamblers they cant control their emotions that's the problem once they start to control their feelings then slowly they will recover from this addictions.
