Right, there are all types of relationships, including where it is fine, or barely tolerable, or absolute freak out justified. As for worry that something terrible has happened, so much depends on the missing person, and the communication and agreement on communications that exists with a couple matters. What’s weird to me is saying you’ve never spent a night apart, in a year, but then without any sign or communication, your SO doesn’t come home, answer calls texts or whatever. Is “independence” really a good reason not to worry, if the SO hasn’t been exerting her independence about staying out overnight for a whole year, hasn’t discussed it, you have not had a fight, just out of the blue? I would ave even worried about an accident at the very least. I would probably call the hospital before the police. I’d also look at the police alerts and the news. Hawaii has Nixle alerts for police advisories. In my 20’s, in the counter culture, calling “the man” was just not done, lol. But that was another time.
