Trust me, you'll never be an empty nester. Your child, or children, will always come back home. Maybe not to live with you any longer, but they will be there. If she's going to college she'll be on the phone all the time, especially if this is her first venture from home. Even after they marry they call home all the time. I'm 65 and retired. I'm busier now than I was when my children were young and I worked outside the home. I have friends that say the same thing. Then once you have grandchildren you'll have them all the time. Enjoy them while you can because once they hit teens they are too busy to visit.
You'll never be an empty nester and you'll find yourself too busy to be an empty nester.
