My MIL is a hoarder, I've never seen inside the house, but from what I understand of it she's a level 4/5. I think she needs to see a therapist about her condition and get professional involvement instead of making FIL clean up her mess. She's still bringing stuff home, and it's expected that every time they visit they'll stay with us (in a two bedroom flat!) because they can't have us up, DS Up, or afford a motel. DH insists that she'd disown him if he tried to make her see some one. DH is aware that his mom is an incredibly invasive and controlling person and still thinks it's a good idea for his parents to come stay for a week after we buy a house. Last time they stayed she brought a ton of useless junk we dd not need. AIBU to say that she needs to seek professional help for her issues before she can come stay in my house?
