phoenix I can certainly relate to the last sentence of your original post. I would have liked, during this horrible time, to at least have the comfort and companionship of a pleasant and reasonably communicative "housemate" instead of a bad tempered and reclusive one.
Enough of my feelings though.
It sounds to me like your husband may be frightened of going to the doctor because he's scared of what the doctor might say.
At this difficult time it sounds like your husband is both worrying you and infuriating you in equal measure. All I can suggest is you hang on to the knowledge that your husband is, as you say, "lovely", "gentle"and a (normally) all round "adorable" bloke, and just hope that he will in his own time get the advice he needs.
Hope things soon get better for you.
