The husband of a friend is almost 80, and my friend is terrified when anything happens to him. She has relied on him for everything ! My friend is fit - we do craft fairs together, drives, doesn't look 74 and is perfectly 'capable'. When I tell her she needs to start taking responsibility, to find out about home finances, to learn how to change a plug, and who to call if the car breaks down, she just shrugs her shoulders. Some people can't be helped, but I know come the day she will just fall in a heap and sink into depression.
I've been alone since husband died 20 years ago, and you have to adapt. Ok I was only 53 but I've never been one to be treated like the little princess and have others do 'stuff' for me. It stood me in good stead for what was to come., and having no children I have had to rely on instinct and a 'have a go' attitude otherwise I would have been stuck under the duvet.
