Good for you for planning those trips anyway! There is nothing wrong with going it alone. I have an ex, but he certainly was not interested in biking, nor are my friends, but I have made friends from the rides I do and from this forum. Just think, bike when you want, go where you want, stop when you want. While it may not be as appealing as you think, there are certainly positives and negatives to both situations. Biking also gives you a "happy" boost which will help you feel better about the things you are going through now.

I second Mr. Silver's checking into local bike clubs. Also check the states around you. An overnight trip for a bike ride with different scenery is fun. Take your camera. Make this all about YOU!
