how to get 18yr old DS to leave home

[Snidpan]

A week after his 18th, he smashed up some gifts, so ungrateful, so hurtful, just one example of his behaviour, feels like it peaked today. He wants to be treated as an adult, then has massive tantrums. Shouts and screams if asked to do the washing up. What options are there to get him to move out?

He starts an electrician course next month

How do I get my 30 yr old brother to move out of my mums house? For her sanity.

It might be worth starting your own thread on this one, but my suggestion is that you can't, unless your DM is willing to tell him to go and mean it

I've been there op with an angry teen who turned 18 and was angry at everything smashed a few things in the house and a lot of name calling he was took it out on me. It was stressful I wanted him to go when he was like that but I would never of let him leave he was my son and there was a reason he was so angry but I didn't know why.
He also threw presents back at me whilst shouting like your dc, I'm not going to go into any more detail but he used to threaten harm to himself in anger but I remained calm stopped arguing back with him on my mum's advice and one day he spoke to me and told me about his years in secondary school and how he was bullied every day the details broke my heart he never told me yet he lived it all through secondary school.
Don't let him leave him op it's hard but there could be something behind that anger that you know nothing about 💐

If he smashes things he does without. If you are giving him money, or paying for his phone, that can stop too.

Stop doing his washing. Or his cooking. Or all the other mum jobs (reminders/lifts/buying clothes) . Give him space to be an adult and see if that helps.

does he have a job? income?
