I am so sorry to hear about Dick. He sounds so much like my Richard. He handled things so well, many didn't realize he was on chemo until it finally caught up with him and he weakened the last couple of months. We found, once he got weak, the chemo treatments were doing more harm than good. I wish we had stopped sooner. The chemo just weakened him so much in the end, he lost his strength to battle back.
I so agree with what Helen and the others who lost their loved ones said: have your daughter come home and spend as much time together. Tell him everything you want to say now. Express as much love to him as you can. But do have your daughter come home.
We were fortunate our sons were both home the last week before my husband died. We didn't know the end was coming until just the last few days. My son tells me now that he is so glad he didn't go to work, and he stayed by his dad overnight, all night, the day before he died. He said those hours were so important to him and he carries those memories with him now that his dad is gone. Please make sure your daughter has those memories and not regrets instead.
I am sending many hugs and prayers your way.
