DH's mum has been very poorly with dementia for years. Has reached critical point where can't swallow now so now being nursed by McMillan. DH 200 miles away but has made journey to be with her. He has called work to let them know but they want to know how long he will be off. There is no definite answer but she isn't eating or really drinking much now. Is he being unreasonable to wait until she passes away or should he be at work. He is worried about his job.
