i'm of the opinion that no kid should be befriending an adult and vice versa. i get that you have the common interest (i.e. roblox) but there is an inherent power imbalance between the two of you. it's YOU who should set and make those boundaries clear. you can start to distance yourself gradually and try to explain to encourage them to make friends with kids his age, not adults.

At this age, kids are quite literally very dumb. The most you can do is warn them, since you both don't even know each other irl. Talk to them with no filter, and try telling them the possibilities of them over sharing and depending on you. The more straight forward you are, the better they'll understand. If they still don't listen, then try ghosting them for a bit or being dry.
I know this is probably not the best place to ask and honestly Reddit might be a better area to ask this kind of advice but I have never used that app before so I’m using the forums here since I at least know how to use this.
Something to know about me before I delve into this is I am in my 20s. This will make sense to mention later on. So I’ve been playing on this Roblox game for a little bit and have been enjoying just chilling and making pretty outfits on it. One day someone came up to me and kind of sparked up a small conversation. Not one to shy from talk I responded. Somehow it lead to this person basically trauma dumping to me and also sharing the fact that they are only 12 years old. Keep in mind I am in my 20s and this child not only shared personal information to a stranger, but some random adult on a video game! I am now absolutely worried for this kid and kind of feel like I had a duty to try and make sure they learn about internet safety and to not be sharing personal information.
Fast forward to like a month and I’m still interacting with this kid because I guess me being nice and worried about this kid’s wellbeing made them want to hang out with me. At this point I’m noticing that this kid is becoming more and more attached to me as time goes on. They apparently told all their friends about me, have been basically glued by my side whenever we play this game, and even been calling me their best friend. Keep in mind, I am in my 20s and this child is 12, I am becoming rapidly concerned that they can get themself in a bad situation if they are trusting to any adult that is mildly nice to them. Recently though, this kid something rather insensitive to another person, the person got really heated and when they got defensive I tried to explain why what they did was wrong. This lead to the kid leaving and unfriending me on the game. Afterwards though, they started to message me rapidly apologizing and saying that they love me.
I’m now realising too late that this kid may have become so dependent on me and that the line of boundaries have been crossed. I have no idea what to do. While I would like to distance myself, I’m afraid of what they’ll do and how it may affect them. They’re a child and I don’t want to cause distress or harm to them, but I also understand that as an adult this interaction and relation that has been built is not healthy for them.
I’m just looking for any kind of unbiased advice or input currently, so any reply would be appreciated.
