Would you consider this reaction from OH odd or normal?

My OH has not asked me anything about a health condition I was found to have in a appointment (four months ago). Two months later the condition had got worse and surgery was mooted.
Doctor advised nothing exertive and no sex.
OH is either unconcerned or has forgotten and has not said a word. I went for another check last week but see no point in telling him the results (which were good) unless he asks.

So, a development in the last few days and I finally asked OH if he remembered about my scans because I got irritated that he was trying to initiate sex. As far as he knew, it was off the cards on doctors orders.
He said that he has been asking me consistently how I am...However, seeing as he actually doesn't know I found this quite difficult to understand. If he had asked me I would've told him.We had a big row from there and he got very angry and defensive and said that I always think the worst of people.
It feels like we're now back at square one but having had a crappy argument about it and both with our original thoughts.

I don't know how to move on now.

Seriously? He sounds selfish and horrible. He should be sharing the burden. I really think you'd be better of without him

You wanted him to ask you specifics and in detail, and he thought general enquiries would be sufficient to elicit the information if there was any. Face it OP, you and he communicate in very different ways.
