My MIL has terminal cancer, she has been given 6 to 18 months with treatment. I don't know how much to tell ds. All the advice is that it is better to be honest, but I don't want him to be sad everytime we see her.
She lives a distance away, so we don't see her that regularly, although ds is close to her as she would come to stop for a week at a time. At the moment she wants to see ds, so we are travelling to see her, although he has picked up something is wrong.
