Can anyone tell me what went wrong?

My thanks to Annierose, cornergran and Hilltopgran - I have already written to her daughter (which was totally ignored, even though I included a stamped envelope for a potential reply) and there are no mutual friends etc, so I am stumped. I did send a card also - same thing - no reply at all. Four attempts at phone calls all failed. My age is 78 and my lost friend is 73. And the strange thing is that both my lost friend AND her daughter were both Witnesses to my original Will, and my lost friend was entrusted with it for safe-keeping, also the code for my Safe. Reluctantly, I drew up a new Will in November, with new Witnesses, as I was very unsure how things would "pan out" as it stood! Regarding the bouquet of Flowers, according to Interflora she demanded to know who they were from, and then literally threw them back at the delivery girl, who left in tears. So I am no nearer in getting peace of mind. But thank you for your kind concern for me XX

I feel sorry for the friend, receiving generous gifts for years and being too poor to match this generosity , she sends a gift and receives a text telling her it doesn't fit and will be returned .

Returning gifts may seem a kind act to the receiver but possibly causes hurt to the giver .

Why dud you need to write a list of all you have bought her?

Reading your post, my first thought as well was Dementia. If your friend is struggling with her memory any new arrangement would not register with her, and an inappropriate gift is not unusual, if her memory is affected she might not remember you and have not been able to understand the flowers were from someone she knew.

As suggested above, a letter explaining how you miss her and are very worried about her is your best option, but you might still not get a reply.

It is hard when you lose touch with someone dear to you, but there is a limit to what you can put yourself through, be kind to yourself and acknowledge the loss of a friendship, and treasure your good memories.

I can understand how upsetting this is. My thoughts echo those of annierose, if there is another mutual friend you could speak to or if at all possible speak with her daughter. If not perhaps let some time elapse and send a card saying that you miss contact with her. it may be that nothing can be done, but at least you will have tried.

Oh dear.
I wonder if this may be dementia? You don't say how old she is (and not always relevant anyway) but the obvious health issues make me wonder, as this is the kind of thing that people with dementia do.
She got muddled about gifts - she bought you something she thought you'd like (getting size wrong also seems to crop up often with dementia) and you 'rejected' it (she obviously didn't understand your practical and straightforward approach)

I know this may not help practically, but I wonder if it gives you some insight & comfort.

I wonder how well you know the daughter? I have often found that 'new' friends are never seen in the same light by children, so daughter may see you as a bit of nuisance, rather than as a deeply caring friend.
Is there any other mutual friend who is still in touch, and who you can ask about your friend?
I think your only recourse now would be a letter to the daughter saying how upset you are and indicating your hope to remain friends.
