My husband's son has moved back in with us after four years in a flat while he was at university. He is supposed to be trying to get a job so he can get his own place again. He doesn't't seem to be getting any interviews, never mind a job. He has had a short-term temporary job. He very rarely goes out as he appears to have no friends. He socialises only when his father or younger brother invite him out to the pub. He showers but his appearance is unkempt - overgrown beard and hair down to his waist. His bedroom looks and smells like a teenagers bedroom. He spends most of the day in his bedroom, where he consumes cans of carbonated stuff and packets of biscuits, cake, crisps, chocolate. He does not normally get out of bed before midday. He does make meals for himself, but not every day. He sometimes eats with us. He was like this before he went to uni. I feel pity for him as I think he has long-standing mental ill-health, but I hate him being here. He is estranged from his mother (his choice). I would just like to read any thoughts that people have about this situation,
