18 year old DS has not gone to university but most of his friends have. He used to be very sociable (lots of "hanging out" after school and some sort of party/gathering most weekends) but of the people he used to socialise with only 2 are still in the area and both of these are mostly busy with other commitments. I think he's been out about 3 times since September; one of those being mid term when all the university people came home for the weekend.
He has a job but most of his colleagues are middle aged and work from home so he only knows them virtually and probably wouldn't mix with them socially anyway.
He chats to his old school friends a lot on social media, but again its virtual.
I'm getting slightly worried that my previously very sociable child is spending a lot of time sat in his room and only communicating virtually. I've suggested he joins local activity clubs to get to know more young people, but he's not interested.
I know he is an adult and am absolutely leaving him to sort this out himself but just wondered if others had similar experiences with their young adult becoming isolated after leaving school?
