My Dsis' son is seriously ill. They live a very long way from here.
When he was first diagnosed, 5 months ago, I offered to drop everything and provide whatever help they needed but she felt they were adequately supported, which was good and fine - her DH's family is nearby and they have lots of friends who have been great.
We did go and visit, travelled there and back in a day, so as not to impose too much and while we were there she complained a lot about people constantly calling to see how he/they were. She felt particularly that both sets of (devastated) GPs and her SIL were crowding them.
Consequently I haven't been in touch much. I keep UTD with his progress through our mum, who still calls regularly. I've sent texts with good wishes at crucial stages of his treatment and I sent gifts for him and his younger brother when he was admitted to hospital but I've hardly called at all. I feel bad about this but also feel that I was told not to call IYSWIM.She hasn't responded to the text I sent on Friday. Not unusual, even before she could take a couple of days to reply. I know all is (relatively) well as she's spoken to our mum since.
We're not especially close, get on Ok but have very different lives and lifestyles and the large distance between us geographically. Before we used to meet up approx. 6 times a year and call maybe once or twice between times. In normal circumstances we would have been at least once more since that initial visit but they have been very busy with his appointments etc. My (our) parents have also said they're visiting far less than they used to because DSis doesn't want have time for them.
I'm struggling to know what to do. I don't want them to think we don't care (we do) but I don't want to add to their problems. What should I be doing now? Of course the "normal" thing to do would be call and ask but she really has made me feel I shouldn't do that.
