It'll be better when you get involved in gambling, just by doing it for fun and not as taking it as a source of income.
Gambling is very dangerous to be taken as fun, the reason why people get involved is that they see it as a way of making fast money and also they take it as a reliable source of income. This courses a lot of issues when someone is addicted to gambling he can gamble with anything hoping to get more of that, this is where they normally fail. Gambling can affect a relationship, if anyone of them is a gambler. A real gambler is never afraid of anything to gamble with, they always have confidence of winning, but still that is the believe of a gambler
Most importantly, people can control themselves when gambling and not consider gambling a source of income. And if they can't control themselves in gambling and instead use a lot of money but lose, that will influence them. He will experience frustration if he loses a lot and wants to recover his losses at that time, but if his wish does not come true, he will continue to think about it. And when he is hanging out with other people, he is still thinking about his defeat and will not focus on his conversation with other people. It will disturb the person with other people because the conversation will be unclear and may trigger misunderstandings. And this will escalate if he still takes his frustration home and gets angry due to his defeat against people at home. And that's where a gambler's relationship with other people will become bad because they cannot control their emotions resulting from losing from gambling.
