Smileless, I have just popped back to this thread briefly and have seen your kind enquiry.
The short answer is that DH's cancer is inoperable and incurable. He is undergoing chemo which has a 30% chance of arresting things, but the treatment is being rationed, so it is vitally important to remain in isolation or the treatment will. be refused.
We visited DD1, SIL and the DGDs a couple of weeks ago which, with hindsight, was the last opportunity. It went as well as it could have done, in the circumstances, although the first day was rather awkward. DH was pleased that we had been and that he had met the DGDs - the eldest one is the image of him and they seemed to form a special bond.
Sorry that this post is all about me, but I haven't read into the previous posts. I just want to wish you all well and I hope Mr S is now on the mend!
What I will say is that present circumstances put everything else in perspective. DD1 is very concerned about DH and is in touch every day. I know that I have to let go of the past and this I am trying to do. I think we all know, in our maturer years, that time is finite. Many younger people know this too so I am not intending to be patronising but, as we get nearer to our Maker, our focus becomes sharper.
We should just try to be kind and to enjoy every day. There is no point in worrying about the things which we cannot change.
