You're very normal. When our first left home to go in the Army, my husband created a shrine of pictures of him on the TV. You'd of thought the son was gone forever. My daughter and I would laugh about it all the time. When our daughter went to college it was okay at the time because she was only 2 hours away. Now when they come home to visit, we love to see them, but it's nice when we have the house to ourselves again! Let's say, you get used to the new living arrangements!
