I think my wife feels ill but I am not going to go home
Why are you not going home when your wife is ill? It seem very selfish of you.
I don't think that it is really a big problem
Since your wife is ill, you should be home and available for her. You are behaving in a self centered and selfish way. Your wife will be very angry with you for ignoring her and not being available to her.
I disagree with what you are saying. I know what is best for me and my wife.
I am not going to persuade you, but I am simply stating my perspective. What happens if the illness takes a wrong turn and she needs help calling 911 but she can't because you are not around to assist or if she needs to eat or go to the bathroom? At the end of the day, it's your call and I will not judge you because you are a good friend of mine, so that is why I care.
