I woke up this afternoon feeling so strange. It’s not my room, it’s not my bed, and nothing feels familiar. My family isn’t here, and suddenly there’s a man, my husband, sharing my personal space for the first time. I don’t even know how to explain it, but I feel like an impostor just walking around and doing things in this place.
Nothing unusual about it. As others suggested, take time to make the place feel yours, through decorating, routine, etc.
This is just something that takes a bit of time, especially since it is your first time in a new home without your family.
My first living away from home was a college dorm, and it did take a few weeks for it to feel like mine.
Even now at 50 moving into a new place feels odd for a bit.
