My second husband had a similar attitude on the few occasions I was unwell - during our 21 year marriage. Normally, he was a lovely, easy going, caring and cheerful chap. He just couldn't cope with illness - at all.
I remember having a severe episode of gastric flu, when I was, mainly, confined to the bedroom and bathroom for several days. He was either out - or angry and stomping around the house. He reluctantly brought me water, that was all. Luckily, that was before the kids arrived and a good friend came to help me.
Another time, when we had two small boys to care for, I had one hell of a temperature and was hallucinating, shivering etc. - as painkillers weren't enough. He looked after the boys, with much complaining, and I was unceremoniously dumped in a tepid bath to cool me down - and told to pull myself together.
That's just a few examples and yes, we did have that talk. He agreed that his behaviour was absolutely awful. His only explanation was that my being ill made him feel really insecure, frightened - and angry. He 'just couldn't help it' apparently.
When he became ill he was awful again - yet I supported and cared for him, the best I could, until he died. If it had been me, he'd have run for the hills (I know it) and somebody else would have helped me.
(Yes, I put up with it - because most of the time, he was lovely.)
