Impala, I did exactly what you are proposing, I wrote a very short note explaining my view of how things went awry. I ended it with goodbye. I got a kind of nasty reply because the truth stings us to the core. What I had to do was tell that former friend of mine which of her behaviors hurt me, and that I had forgiven her for them. I actually felt better.

I heard from her one more time a few weeks later, telling me that she misses me. I did not reply because I cannot face a "friend" who can't take responsibility for her own actions. I still struggle with it every day and somewhere deep inside, I wish that she would apologize for what she did. But I do understand that in her mind, she did nothing wrong. Hence, I cannot have that friend in my life because I do not allow people to treat me that way. Her way.
