This is a slightly sensitive subject but goes in to no details, so hopefully no trigger warning needed.
On Friday my sons paternal grandmother was diagnosed with breast cancer. The diagnosis is still early and raw, as you can imagine, and I am very grateful she took the time to let me know (well she told me dad, who told me, as I wasn't there to collect DS).
I text ex-dp (son's father, who still lives at home) and ex-mil (never married but easier acronym) to say how sorry I was and how I'd be there to help with anything concerning DS.
Ex-dp has completely ignored me, his mum replied with thanks. I don't expect anything as it's going to be a hard time for them, they've been in my life a long time and I do care for ex-mil but my main concern is DS and how he'll be.
Ex-mil is waiting to find out more about her treatment, options and prognosis and isn't wanting to say to DS now, which I understand and agree with completely. My aibu is that neither ex or ex-mil are sure they want to tell DS at all. Although not my illness I think that at a point he should be told. He's 8, he'll notice changes in his dgm, he'll see her ill and she will, more than likely, be in and out the hospital. He stays at ex-mils during contact, she collects him etc. He is very close to ex-mil. They want to protect him but I think lying about it will do more harm than good.
Obviously I'm not going to step on any toes but, in time, I want to say that I'd explain it to him to save them the upset and difficult conversations.
Aibu to want to tell him, when the time is right?
