vaginapagina | Resources for safety when dating

Sorry for the weird title, wasn't sure what to say. My best friend and I live in different states and are both on dating websites. We've been going on a few dates here and there and we always tell each other where we're going (name of establishment and town) and text each other when we return home.

But my question is... If something were to happen and we didn't hear from the other person, what do we actually do? Call their local police and ask for a welfare check, and state where we last knew they'd be? Would they search for the person right away or do they brush it off if it hasn't been X number of hours?

Just wondering what resources or ideas are out there for this.
