You are not crazy. There seems to be a lot o evidence of your friend alienating people. It is possible to forgive the person and still stay away for your own sanity. Being a good person or a good friend doesn't mean that people get to tear a chunk out of your self esteem when ever they feel like it. Relationships are not meant to be one sided. For me forgiveness and self respect are not mutually exclusive, I wish I had known that all along. Most days I manage to wish my XABF the best of luck I'm just not going to show up for the verbal abuse anymore.
