What do you think If I told you I'm tired of my wife being sick all the time?
I'm sorry to hear that but why are you upset that your wife is sick?
I'm busy, she doesn't really do anything for me. What does she do? Just sleeping all day.
It's not okay to be upset with a sick partner. Maybe you can help take care of her so she can feel better. That way the two of you can do more for each other.
I could, but she doesn't deserve being taken care of.
Don't forget your vows: in sickness and in health, until death do you part. I am sure she doesn't want to be sick and slept in all day. It's unavoidable when you are sick, so you should give her the benefit of the doubt and help her get healthy as soon as possible.
