@Feelinghurtppp,
In the course of the last 3 years, has he never worn a mask, used hand sanitizer, or washed his hands with hot water and soap while singing the Happy Birthday song twice?
All of these things prevent viral transmission from viruses which live on surfaces -- which cold and flu germs do.
If he does all that and doesn't kiss you, then it's not likely that you would pass him your cold.
And if all that is oh so difficult for him to do, he has a phone, yes? Then he can contact Doordash or Uber Eats or the like and have a local restaurant deliver soup to you.
Hell, even if there are no such restaurants in your area, IIRC GoPuff will deliver stuff like tissues. CVS sure will, and I bet other large pharmacy chains like Walgreens and Walmart will, too.
He probably didn't think of these out of the box ways to show caring, so it's up to you to clue him in.
PS do NOT give up your home. Rent it for passive income but keep possession of it in your name ONLY. If you're unsure of your relationship and its future, you will be a far happier person if you hold onto sole possession of what is likely to be your biggest asset.
