Such things happen naturally when a person starts gambling in a new situation, no one can understand it at first. When they lose all their money and see bad aspects in their behavior, that is when they understand that the person is addicted to gambling. There are many people around us who are addicted to gambling but their families are not able to understand it till now. Only when they lose all their money and sell their assets, that is when they will understand that they are addicted to gambling.
Yes, but the point is that it could happen with anything that destroys the family or the family unit.
Even alcohol, or smoking, or drugs. The point is that addiction to anything destroys everything.
If you're playing normally for fun and a chat at the bar, i don't think it'll cause any problems. My partner and i had an experience.
