It is not your adult children's job to be there for you. They are not responsible for your happiness.
I totally agree that we cannot be responsible for anyone's happiness, and that applies to our relationship with our adult children. However when we untie the apron strings do we also give them the message that their parents don't matter any more?
I find it very strange that Brenda's adult children are not aware of how she feels or have tried to suggest solutions. Although they cannot be there they could be giving her the advice and support we Grans are giving her here.
Couldn't they?
Sometimes all you need to know is that you matter, and your offspring care. It isn't a burden to love your ageing parents is it?
They cannot travel to be by their mother's side in her sadness but they could be talking through what is going on in her life - and theirs and maybe making plans which include her, now and again.
My children have lives of their own (and I am glad of it and would have it no other way) but I remain part of their lives even though they are busy. Again, I recognise that our relationship with our families are different, but many of us were busy full time workers too when our children were small. Our generation tended to check on their parents' keep in touch and know what was going on in their lives.
I agree, if we possibly can we have to row our own boat in later life and try to remain self reliant and make some sort of life for ourselves - I have no query with that, I just don't get the "They have grown up. They can ignore their lonely mother now because they are busy and you shouldn't expect them to be involved in your life, even if you are sad" response, I really don't.
