asking if he is ok is fine. adding the 2nd part is just setting yourself up for angst.

if he replies with a snotty answer you'll be upset.
if he doesn't, you'll be upset.
i assume he is old enough to respond/not respond & make that call on his own.

it feels like you almost wanted the bad contact just so you could continue the drama

let it be or send a "hope you are safe in this weather" text and leave it. no expectations from that other bthen someone is home safe. period.
