Hi Whatif,
Well done on your gamble free time. Well done on making it clear that you weren’t going to the casino. You will find out who your real friends are and who might have just been gambling acquaintances. A few “I’m not interested” or “I don’t gamble any more” s usually stops the gamblign conversations. Maybe have a word with your brother in law or get your wife to sort out her brother!
Be careful with the drinking. It is easy to swap one problem for another. Also of course alcohol can weaken our defences when it comes to gamblign as well. If you are planning on having x number of beers or staying in the pub for a few hours then go with enough money in your pocket for that number of beers only. It will help you in more ways than one.
Keep posting and again well done on your gamble free time.
