Sounds like my bloke, when he's ill, he talks, or rather mutters to himself,
says he didn't sleep well, when I know he did, and won't take anything only painkillers.
No honey n lemon, no cough medicine, no nothing! Lol.
I used to worry, but now I don't, I let him get on with it, trouble is with lots of men , the more we fuss over them, the more they act.....they're like children.....
Your hubby though is probably scared about getting proper Ill again, (cancer) and is reliving some of that.....xx
