The match ended with a win and we were both happy. Personally, I wasn't concerned about receiving any money from him as I was more focused on my recovery to not set a bet or deposit ever again. However, the next day my friend avoided me and didn't follow through on his promise even though I wouldn’t have minded if he didn’t.
What I took away from this experience is how the mentality of gamblers can change after a win. The thrill of success often leaves us wanting more and in this case it seemed like my friend was caught in that cycle, as I was feeling before too and he was unable to honor his word probably because he wanted to keep increasing his gains and bet more. It's a reminder that the brain is never truly satisfied when gambling, there's always the desire for more. I believe that friend deserves an advice, but I don’t want to embarrass him myself, is there a good way to talk to him without making him feel that Im indirectly asking him for the money he promised me?
You've not seen nothing yet. What is that saying again that money brings out the true colour of people. It's valid here. Your friend is just that way, needing both your physical and emotional support when he was vulnerable, but when he achieved his aim, feels your importance is over, you're good for the process and not the dividend.
It's a very wrong mindset if it's intentional and it advertised him as both greedy and stingy. He's not a good team player, for me his behavior explains more of his personality than just avoiding to live up to his promises.
