I've known several gambling addicts down through the years, the damage they did to their financial and family lives was tragic. Divorce was almost a given, homelessness occurred on several occasions. Being shunned by their parents and siblings sometimes followed after money was borrowed and never paid back.
Two things I never could understand after all the above. First, I couldn't get any of them to attend GA meetings after I offered to attend with them and second, why they ever thought they had a chance to win consistently in any gambling endeavor when the gamble itself is connected to a computer. (Yes, I'm saying cheating can be involved. Imagine!)
These two are not at all the same, and one is much more dangerous and asocial than the other.
