Badger, I'm sorry you lost a friend, but it sounds like you did the right thing. I've broken up with a few friends myself, usually because the degree of crazy just got to be too much for me and/or they didn't reciprocate my friendship in some fundamental way.

I do sometimes feel some degree of regret or guilt over the break up, but I just remind myself that that what I miss is the idea of their friendship. Once I factor in the crazy or hurt, I remember why I walked away in the first place. It is sad to lose a friend, though, even when it's the "right" thing to do. Hang I there. I always spend extra time lovin' on my pets when I feel down about a friend. They remind me how nice it is to be loved and to love in such a uncomplicated manner.
