husband has bad cold.

my husband has a really bad cold and he slept on the sofa last night as he was so worried about me getting it and delaying my chemo. I was worried about him as I have never seen him look so poorly so I didnt sleep well. Should he just have come to bed as its very likely I am going to get it and we should carry on as normal or is it a good thing for him to stay downstairs until he is feeling better I have wiped everything I can do with antibac but surely this is just going to be a viscious circle? 

Gosh, I don’t know what I’d do. That’s no help really, is it! That’s v considerate of him to sleep elsewhere, though. Thinking about it, that probably was the best option. Hope he gets better soon.
