My SIL is 46. She is DH only sibling. SIL Is single, possibly gay, has high functioning ASD, private school and university educated, no assets, a history of failed careers and had returned home in middle age giving her parents a list of unpaid debts and bailiff letters to sort out. SIL is back in her old bedroom and trying to get any kind of locally paid work. DH and I feel she's a ticking time bomb. In laws are getting older, running out of money and energy to deal with her. Does anyone have any advice on dealing with family members like this? We've suggested citizens advice etc. We've our own kids and life worries to get through.
