If we want someone to share our life with, we get married. If we want to make a life for someone else, we have a child.

Though you're going to miss you child terribly, you'll do what all good parents do - sit back and watch them make a great life for themselves. Their purpose was never to make your life, but for you to make theirs. You've done it, and done it well. Now that's something to be proud of.

You now have the choice of living it alone or if it's time to add someone to your life as a partner or companion. I'm hoping that you'll share yourself once again, but this time as an equal partner so you can make another great chapter in your life, but as long as you're whole life is built around your kid, then why ever go out and make one for yourself? All single parents hit this stage, but it's their true love that makes them have their kid leave the nest so they can do some amazing things that you helped make in the first place. Best of luck, Bob.
