I gamble alone, not because I prefer it that way precisely, but because of pure chance. In fact, some of my friends love betting on sports (on sports that I don't like, unfortunately) or gamble but in platforms or physical locations I don't like. So, although I would like to have some friends I could talk to about my gambling experiences, the most similar experience I find it in this forum.
I am the same as you. I gamble alone. Because I like to enjoy casino games but my friends like sports betting so I don't have any discussion with them about gambling. And when I lose money in gambling my friends scold me. They say that sports betting is easy and you can win easily there why do I play casino games which are very risky. And I don't tell them anything. I enjoy casino games alone. And the reason is that casino games can be played anytime and are very fun.
