My brother who is a chronic alcoholic, has been thrown out of the marital home by his wife. She's been at the end of her tether for a while. They are in their 50s and she has one adult child who at the moment is also living in the house. He's recently been seeing the drug and alcohol services but is not complying with the home detox programme. He drinks continuously. He is never sober at the moment. Fortunately he's not aggressive. Unfortunately he's moved in with our very elderly father who is showing signs of cognitive decline and dementia. Under normal circumstances they get on well, but with his erratic behaviour, this isn't fair on dad and in allowing him to live in the spare room, I feel that Dad is unwittingly enabling the continuation of the alcohol abuse. We don't know where to go with this.
