I think the in-universe reason she wouldn't try to figure out where Hook is is because she doesn't want to know. When he doesn't show up that first night, her emotional brain jumps to the conclusion that he's abandoned her. The percentages her brain have come up with are: and those aren't odds she's going to want to deal with.
 * 33% chance of finding Hook looking much happier than he ever was with her now that he's a free pirate again
 * 33% chance of finding Hook murdering Snow's fourth cousin thrice removed
 * 33% chance of finding Hook making out with pirate-loving broad #365
 * 1% chance of finding Hook trying his best to get back home to her
