(((Rose76))) that is a heavy load to carry. I understand, I volunteer in this sector and see situations like yours quite a lot.

I think you are wise not to take on too much responsibility, social services can see someone like you and although it is not right they can assume a lot, a willing horse and all that. Support as a friend is one thing but court appointed guardian quite another.

Please do not take this the wrong way, I realise you are not trying to threaten him but acquaint him with the reality of the situation but it's possible he may be at the point where his reason is affected by the disease. Please remember it may feel personal but he has a disease which is changing the capacity of his brain to understand and empathise with others. It's also common for people with dementia to also suffer with depression which can also add to lack of motivation which may explain the shaving situation.

Are there any clubs/groups in the area where you might go to socialise with others in similar situation? Sometimes being with others can help lighten the load a little, even if just to know you are not alone.

Sending big hugs to you.
