If someone close to you had a serious illness and the probability was that their life expectancy was less than five years, possibly less, would you want to know? I was in this situation with my Dad five years ago. He was given six months to live and my Mum hid the fact from us. As it turned out, he is still with us (and I hope will be for a lot longer) but I would rather my Mum had been honest from the start. I'd Googled his illness anyway and knew that life expectancy was not good. I'm now in the situation from the other side as my MIL does not realise how serious my DH's illness is. She is convinced he is going to recover fully. I really don't want to tell her the truth - she's an old lady with health problems of her own - but then remember how angry I was with my mum for hiding the facts from me. What would you do?
