Re: Men, would you cancel your plans if your wife got sick?
Don't make any decisions, or confront him with any suspicions, etc., until you are completely recovered and are thinking rationally [ie, not fevered and wiped out physically]
Get all kinds of fluids in you.
I've don't think I've ever heard someone here say "I think he's getting advice from somewhere" without having a good reason to think that. That is a strange thing to sense. Once again, wait until you are back to full health before you act based on this impression. It could be your intuition going off, or it could be feelings of vulnerability resulting from your body combating high fever, vomiting and severe pain.
