85 year old MIL and FIL, FIL has dementia and is unsteady on his feet, MIL has osteo arthritis and physically frail. Mil would like to go for a few weeks respite as she is mentally and physically exhausted with looking after FIL who is repeating questions, has lost the ability to deal with finances and is becoming aggressive with her.
FIL will not accept any help and says he'll be fine home alone for 3 weeks whilst MIL is in respite. We have had to say MIL is going to hospital as he will not accept she needs any help. He refuses all suggestions of carers, cleaners, meals service, a 'hotel' for a holiday, care home, won't go to social groups, won't allow MiL to go out without him and becomes aggressive to MIL if the subject is raised. He can't remember to take his medication and forgets how to make a cup of tea, he has not cooked a meal by himself for over 30 years.
We are terrified of a crisis happening whilst MIl is in respite and not sure what we can do. We have power of attorney. All suggestions welcomed!
