In the past year my ex H has taken our ds, just turned 16, over to Europe for a night. Each time he has left ds about midnight alone in the city centre while he goes back to the hotel. Ds thinks its odd, would rather his dad stayed out but would rather stay out that go back given choice. When I go away with ds we go back to hotel at an agreed time between us.
I realise he is now 16 but I find ex's behaviour weird. My main worry is ds has never been to either city before and was drinking beer alone. If he had a friend there then fine.
AIBU to find this an unnecessary risk, especially as ds phone is not international.
