Maybe you could find a riding buddy. Many of us love to ride alone, as I do, and that's how I learned to love riding--going out by myself for miles and just riding and thinking. But last year I acquired a riding buddy, and I love riding with her, too. It's just a different experience.

You could check with your LBS or see if there are any clubs in your area with a slower or beginners' group. Maybe you just need someone to share the ride with.
