Base on my experience ot is really hard to quit gambling specially when you are already used to it, before my parents will get mad at me becauase I forgot my responaibility as a mom also they sees me almost broke because of being addicted in gambling. One day I realize to quit gambling and I really want to do it so by the help of my love ones and determination to change I now stop or quit in gambling .
You still can be a responsible family member while doing gambling it is all about having limits managing our daily life.But most of the people will fall entirely into gambling which results addiction so if you can't limit it then better stop it.
The falling entirely into become an addict is where the problem actually lies and the fact is that virtually everyone that just keeps gambling with what they could have used into doing something tangible and they still keep losing are actually their own problem. Definitely, things like this will affect the people that are married and as long as that is in play, that is a huge act of irresponsibility on such a person's part and like you said, for those who simply cannot control themselves, it is better to stop than get extremely engrossed in it.
