Well, it seems she's already made one mistake by losing in gambling, and now another by venting on social media. You can really see how desperate she is, and it's clear he's in some serious trouble as he's making decisions that aren't ethical anymore. The thing is, once those mistakes are made, there's no turning back the clock. At this point, it's the family's role to provide comfort and support because this is when family is truly needed.
Addiction can be a real financial and life-wrecker, especially in gambling. It's something that shouldn't have happened in the first place. That's why emphasizing education and discipline in gambling is incredibly important to prevent this from happening again.
Before we jump into addiction, I'll want to agree strongly with your point on she been in serious trouble. People loose money from gambling daily and we don't hear about it neither do they flaunt it on social media except they're dragging a possible Telegram group owner for supplying them games that turned south. But in her case, I suspect she used funds meant for another thing to adventure into gambling and that hurts deeper cos she has to not just live with the loss but also work to replace the lost funds. I just hope its not tuition fees though.
