How common is this? My partner is useless when I'm sick. He's not remotely sympathetic, can often be actively hostile, and certainly doesn't help me or try to make me feel better, except in quite a half hearted way if I point out to him that he's being an arse. I know part of it is that he's very black and white, so unless I have an exact diagnosis from a doctor, with prognosis and aetiology (!), he gets frustrated and angry. But I tend to wait and try to figure out if I should go to the doctor or not, some things pass in 24 hrs and don't need medication, but are just as painful and unpleasant as diagnosed illnesses. I know he thinks I'm being a drama queen if I complain, but if I don't complain and try to get on with it and he catches me wincing or something he gets cross as well.
But, when he's unwell, I look after him, bring him stuff and make sure he has medication, and he is very quick to let me know all about it! He calls me a hypochondriac, but I truly don't think I am, I don't get sick much. But when I do he seems to either think I'm pretending, creating drama, or doing it to annoy him.
