If your son has ADHD and possibly ASD, to expect him to move out when he completes his course is unrealistic. From what you have said he has had no training in independence skills, you have not trained him to live independently, he doesn't pay rent, doesn't help around the house, has meltdowns, and needs medication.
My son had a similar diagnosis and even WITH training at home and his special boarding school 15 years later he still struggles. ASD doesn't suddenly disappear any more than ADHD does.
To manage alone you should be helping him to budget. To share bills, rent, and food costs. You need to teach him to cook, to maintain his clothing, safety and organisation of his home.
I'm not sure why you posted but I feel sorry for your children you may have paid for them, but that apart I can't help but wonder how you have supported your children into adulthood.
I agree. Trouble is, if the son is “resistant” it’s going to be difficult to get him to accept such teaching. Our own ADHD/ ASD son had to return home to live after uni because it is crazily expensive to live on your own. He got a job, he offered rent but we didn’t take any and he eventually saved enough for a deposit for a house share and after a promotion, was able to move out. He lives and works in London and there are plenty of adult children living with parents and even wfh from their bedrooms.
Our son actually learned to manage his life admin far better than my OH ever thought he would, he didn’t think he’d be capable, and our son is doing well. If you are able to help them move into flats, that would be great as long as you step back after that. I don’t think my son helped at all at Christmas but has transformed into someone who helps clear away and gives and even gift wraps great presents! Living in an adult world of independence has done him the world of good while living at home kept him infantilised and quietly depressed.
You have my sympathy but don’t despair
