Two things going on.
Ds is 16, he'll be 17 in May.
He has been invited to go on holiday abroad with his gf and her family in Summer 2025. They've been together for around 8 months but they don't actually spend much time together. She also breaks up with him then wants to get back together. I'm not keen on the idea of the holiday but don't really feel that I could say no as he'll be 17.
The other dilemma is that I want to
Go on holiday myself with dh and ds2 who is 12. Ds1 has ruined nearly every holiday we've been on in recent years with his bad moods and general being stroppy. He doesn't enjoy going with us anymore no matter what we do or how enjoyable we try to make it.
He will just sulk around with a face on him, wind his brother up, not get ready and make us late just being an absolute pain in the arse.
I don't trust him to leave at home either. He'd be capable of looking after himself but I'd be worried about the house being trashed.
There's literally no one he could stay with.
