My hubby is pretty good when he is sick. He rarely gets so sick he has to go to bed and when he is that bad he wants to be left alone. He isn't a bother.
The problem is when I'm sick. He thinks I'm like him - that I want to be left alone. The problem is, when I'm so sick I am in bed, I really am so sick I can't do anything for myself. As my husband said, "I noticed that when you get sick you tend to let things go around the house." Well, yeah! One time I was so sick he moved me out of the bed onto the couch, then left me there. He'd leave for work and not even offer to get me food, water or medications yet I was so sick I couldn't get them for myself. What I really needed was to go to the hospital - and he was leaving me alone all day while he worked!!!
Over the years he has slowly gotten better about being aware when I'm so sick I can't even talk but years of him travelling has forced me to work out a support system that doesn't include him.
