Brad:
To me it depends on what your motivation is to be alone. Are you doing it to try and escape facing up to challenges/realities that you'd rather not face? Or are you doing it because you enjoy it and function better on your own? There are plenty of ways to be out and about and engaging yourself with others without actuallly making long-time friends or relationships if that's what you fear. Volunteering, attending community events, churches and associated groups, there are a multitude of things you can do where there is no long term committment to other individuals.
