Merging fully-equipped households can be a chore in the best of times. In the worst of times, it can lead to bickering. Whose kitchen table do we keep? Which dresser do we use? Whose toiletries get prime counter space in the bathroom? And don't even look at the spice racks or the utensil drawers. Those are potential arguments waiting to happen, depending on how seriously you and your significant other consider basil and forks.
If you're going through a situation akin to this, being disorganized won't help the issue in the slightest. Want your centerpiece on the table? Your picture on the wall? If you can't find them, they'll likely lose their spot. So if you find more and more of your possessions have gone missing and are being shunted to the side because of it, that could be a sign you're the more disorganized of the duo and need some lessons on the subject.
