My mum is in the mid-stages of dementia. Her short term memory is very bad and she is very anxious and confused a lot of the time, particularly at night. Last week, her (87 year old) partner (who also has early stages of dementia), left her. He literally walked out of the house and is refusing to come back. We understand his decision as he was really struggling to cope. However, my mum is really confused and asking when he is going to come back. We are seeing a social worker tomorrow and she will have to go into a home as she cannot stay on her own. But we feel dreadful, not only that we cannot look after her but, have to somehow tell her he is not coming back. Does anyone have any idea of what or how we can tell her?
