Hi @geoffnc and welcome to the community though sorry to head about your wife.
Any cancer diagnosis is shocking and often has a significant impact on those around them, I recognise this from the time six years ago when my wife was diagnosed. Being a carer can be tricky too because we do not get to make the decisions and it can sometimes be difficult if our other half makes a decision we do not understand.
You might like to look at I'm looking after someone with cancer and especially the emotional bits; their have been times I have cried buckets but for now my wifes cancer is stable, she is in great health and life is good.
Remember to make time to look after yourself because you will do the best job of supporting your wife and remember you are not alone.
<<hugs>>
