To play devil's advocate, I will say that I kinda see where it's coming from.
When you look at literally the entire rest of the gambling landscape, what do you see? Guys lighting their money on fire. The ones who get more and more into it, they burn even more money. They chase that big win they "know" is coming, day in and day out, or screw it, they don't even understand why they do it anymore. They just can't stop.
I get how poker can be different. You get it too. A solid portion of poker players do. But some guy's wife who never plays cards? She doesn't see the limited, social aspect or even the profitability, if he's a good player. She just sees blackjack, roulette, slot machines. She sees her husband throwing away their family's future. Even if he's a long-term winning player, she can't really trust it because she's expecting secrets, lies, and other addict behavior.
Still, that's gotta be extremely frustrating, to not be able to get through to the person closest to you like that. And the more it seems important to you, the more it looks like you're just a compulsive gambler.
