I would agree with this if he is contrite, and realizes he's put them both at risk, and is apologetic. Has he asked for a one time pass or a season pass?
If there's a disconnect between what Rianne and her DH now consider acceptable, there's a long conversation to be had.
I have been wondering what would happen - as I'm sure is happening in many homes - when partners aren't on the same page for covid-re-entry. It's bound to create some conflicts. I'm personally a little less risk-averse than DH, but I figure his comfort level is where we set the bar. But as for restaurants, he's happy to go outside to our sushi place each week, and that works for me.
