Am I silly for worrying?

Florida has a stay-home order from the governor as of yesterday. my boyfriends brother texted me saying “i’m taking a road trip to North Carolina to see my friends” and I started getting extremely worried and i told him out of any other time, you choose now to go on a road trip like there isn’t a sickness going around. He says don’t worry about it and he’ll be fine.

He most likely will be fine, but i’m just so worried.

Then he said i was a dumbass for worrying (He was extremely upset with me for telling him it’s a bad idea)

He says he did it because he feels like it and he doesn’t give a shit what anyone says

I’m not stopping him, obviously since he’s in another state... I just want my (basically) brother to be okay... 😓
