I was out clubbing and drinking alcohol at 12, having sex and taking drugs at 13, homeless by 16 and a single parent at 18 living alone with zero help.
But there is no way I would leave my 16yo DD home alone for the weekend, especially when unprepared like this because I’m not a negligent parent and my DD (and most teens now) are emotionally much younger than when we were kids.
You trusted someone to look after your child and they couldn’t even do that, it doesn’t matter how old they are.
Of course there is a big difference between leaving a 3yo and a 15yo for the night but it’s still a shitty thing to do.
I completely understand why you’d be so upset and panic over this.
I think MNers are being very unkind.
It’s different if you were an hour away but any decent parent would worry about being so far away.
Your son will be absolutely fine though as he is safe in his home.
As long as he’s got food, toilet roll and the internet, then he’ll be fine.
I would not return early unless DS is really struggling.
I would rethink the relationship once you get back (don’t worry about making that decision now).
