When your husband returns, there are precautions you can take, for the 1st 48 to 72 hours he is back home. If he doesn't become symptomatic then go back to normal....
I do that when my husband goes on business trips. When he 1st returns home from the airport, we both wear masks in the home, and he goes in and showers and changes his travel clothes and puts on clean ones. And we socially distance on the first night ----The same with the next day.
I keep my distance from him, politely, until we make sure he is not going to be symptomatic. We still talk, and eat together, but outside on the patio and across the table, etc. But he sleeps in the guest room until he waits a few days to make sure he isn't contagious.
I do have to protect myself because of my lung issues. After 2 or 3 days I go back to normal married living habits with him. It makes me feel safer because he is the one traveling in airports, going to business conferences, etc.
