The bond between child and parent is much stronger than in marraige, when i had my stroke my wife was quite matter of fact she said very clearly she did not want me back. Do not believe all this rubbish that something has to be wrong before the stroke for the partner to leave, not in all cases. In the hospital a vicars wife said again for all to hear, she did not want him home, i can give you any number of cases.
My elder daughters did not even have to be asked but very clearly said we want to be with you and they still are. They look after me through the mood swings and are understanding beyond their years. The oldest one goes off to university, still staying at home, next year to be followed the next year by her sister.
I think i am truly blessed to have two lovely daughters, pity i did not choose my wife with such care.
