Just a thought as to what you can do ................................ go to the nearest pharmacy and get yourself some of those throwaway masks.
Start wearing one around the house, when he questions you, your reply can simply be:
"Well you feel seem to be so miserable, for all I know you have the swine flu, so I am just protecting myself."
Any further comments from him, you can become a broken record, saying:
"Gee you better go to the ER and get yourself checked out."
Over and over and over.
He'll either shut up or go to the ER to find out it is just a cold.
Just because he is not drinking does not mean you will see a 'sunny side' of him, as actually he is probably more miserable detoxing all the booze and whatever else out of his system, he would be miserable even without a cold.
Now might be the perfect time for you to check out some Al-Anon meetings. Not only have meetings helped me over the years with my own issues, I have also many times found 'help' from members for some of lifes problems ie a place to stay, a job offer, someone who was willing to sell me a car on payments, all sorts of things. It sure helped me a ton to build that network of friends and acquaintances in AA and Al-Anon.
Please keep posting and let us know how you are doing as we do care very much.
Love and hugs,
