Feeling concerned about DH's family. For the record DH is embarrassed by this and tries not to involve me in any of his family or worries. He is also the most lovely and generous man; whilst one of his best characteristics can also be a fault.
We have two children and niece (DH deceased sister's daughter living with us), she is a young adult and like a second daughter, she's been living with us for 3 years.
SIL has mental health problems and is an alcoholic. Periodically goes to rehab but often goes back off the rails. In the twenty years I've known her she has never supported herself, she has always relied on a man or family. For the past 2-3 years she has been living with FIL who pays for everything, her medical bills (they're abroad and her medical insurance is high), he's put his property in her name and pays for all her food etc. Over the years he's found her many jobs which she never sticks to. Her alcoholism and mental health means she is incredibly manipulative and difficult and often cannot get out of bed for days. Essentially she doesn't function as an adult.
Fil wants to go into a home and is quite unwell and she recently lost it with DH and FIL and rewriting history when they suggested she must support herself. She was horrible and manipulative and frankly behaved appallingly, rude about everyone and used Facebook to slate FIL which was horrible.
I understand her life is bad and that mental health is terrible but I do not want her to become reliant on us (financially or administratively, or god forbid love with us which has come up in the past). DN could not live with it as she's been through so much already and I don't want my children to either. We also have no savings etc and I don't see why we should have to fund her. AIBU to say this should not happen? I'm wondering if it is heartless and whether if she had to survive she might actually manage?
