What to do when you can see it's happening, but the one being coerced can't and is likely to react badly to having it pointed out?
My cousin's daughter (mid-twenties) has a friend who is around all the time. Almost constantly. The daughter had an operation a couple of weeks ago and the friend pretty much took over whilst she wad in hospital. My cousin and her DH, who are caring, competent and loving parents, are being pushed out. They know little of the Consultant's prognosis, etc., and whilst the daughter has returned home the friend continues to be taking control of all aspects of the daughter's life.
The daughter has a strong character and personality. My cousin is no weakling on the character front but the daughter is the more opinionated of the two, which makes this coercion hard to understand and hard to break. Going about it the wrong way will likely result in the daughter going to the friend's place and being ever more controlled.
Cousin needs a way to open her daughter's eyes without alienating her.
Any and all suggestions much appreciated!
