Mudbug, once your kids are adults, they don't need to "come home" to a place where they are known unless they want to enough (i.e., they can stay with aformentioned friends or get a hotel room). So once she graduates from high school, feel free to move on. It will free her to be a real adult, and help you to move into the next phase of your life. I have three younger sisters (two in their forties, one in her late thirties) and somehow we all survived not being able to "Go Home" to the house we were raised in. So -- go for it!
