Apologies for the long post but please help me to understand if I am overreacting as I have no idea how I am going to sleep tonight or ever again in this house.
DS (17) has never been able to develop friendships at school and whenever he is placed in a social setting he comes over as much younger than his real age and is so desperate to be liked and to have friends that he does have a habit of over-sharing and trusting people who he probably shouldn't. Over the last 12 months or so, since leaving school, he is spending more and more time on his phone, which has exponentially increased this risk. I am not active on social media, but as an example in just a couple of months he has developed a network of thousands of "friends" on Snapchat largely from adding random people who he has never even spoken to and then blasting them with messages. Some respond and he immediately thinks they are his friends. We have been able to protect him from some obvious trolls and catfishes, but I am worried that he is now putting us and our other DCs at risk.
By way of background, as a family we are comfortably off and we do have quite a big house with a few acres of land in the countryside, about seven miles from the nearest town. However, my DS has no concept of money, and now seems to have convinced himself that we are millionaires with lots of cash to splurge. I don't know if he really believes this or if it is part of his fictional life to make himself more popular with his online "friends". We have explained to him the reality that we studied hard and worked hard and we have been very lucky, but we are really not rich by any means.
Anyhow, tonight my DD (14) came downstairs and said that basically he has been sharing messages via Snapchat and other SM sites with loads of people in the UK and overseas telling them that we are millionaires and how we have this huge mansion full of amazing stuff. The thing that really terrifies me is that when people came back to him online and either did not believe him or asked for more information, he has been sending them the precise location of our house, which is in the middle of nowhere.
DP and I have tried to explain to him how dangerous this is, but he just thinks he is being honest with people and that we should be proud of all our stuff and he really doesn't understand why we are worried.
I do think this is all part of him trying to show off to make friends, but I am now genuinely terrified that some random people that have seen or heard about his online messages are going to pull up outside our home at any minute to help themselves to all this amazing stuff they think is in our house, and god knows what they will do when they find our younger DCs asleep in their beds.
How on earth do I get DS to stop posting these crazy messages, which are already out there and can never be taken back anyway?
So please, tell me, AIBU and this is just a teenager being a bit silly and nothing will happen, or AINBU to be scared for the safety of my family and home and this fear could continue for as long as we live in this house as those messages including our location can never be unseen by any dodgy characters that have seen them?
