MY ds who is 21 lived at home whist he was at university and commuted, DS has ASD and is high functioning. Since finishing his degree this year DS has said that he feels he didn't give much thought at the time to considering living in halls when he went to university as at the time he thought he might find it challenging.
DS has recently said that he wonders whether he should have tried living in halls and come out of his comfort zone but he's ok with the decision he made to stay at home. I've read threads on mumsnet where posters have said people who commute miss out overall for the university experience.
When lockdown first happened all of his classes moved online and it stayed that way for the rest of his degree meaning DS did not see any of his course mates ever again leading DS to feel a bit isolated and he has not met up with anyone of his age since the first lockdown started.
