My husband was out with 12 work colleagues for a work lunch. He messaged me at half 5 to say they were finished lunch and moving to the bar. He said he wasn't drinking and he was leaving soon. (He works away and stays in a house we own in that city) He isn't there I can see that from security cameras. I haven't heard from him since. I have messaged him and heard nothing. I'm worried something has happened to him. It's not like him to not at least send a message.
AIBU to be worried? What would you do?
