It's a really bad habit for some players but it's no different from any other bad habit used as a crutch. He'll definitely stop if he gets a gf as his money is finite and his life choices would have to be balanced in order to keep and impress his significant other. Just a thought.Also close or not when someone is deep into anything be it drugs or any addiction retreating is not uncommon so that's also food for thought. Keep trying man and perhaps you can find a way to drag him away from the game for a while or often enough. For example working out together. Men especially get rewarded with endorphins this way. A similar rush that he'd get from buy shit. Anywho you're welcome. I hope you the best of luck man and thanks for being a bro to a bro.
