Writing a letter is good for "you" Werewoman, it's a way for you to write down how another person's behavior hurt "you". The one who needs the healing is "you" and often the people that hurt us in some way simply are unable to be receptive to "our" hurts otherwise they would have never have hurt or betrayed us to begin with.
I could NEVER ignore it if someone hurt my daughter in the manor you have shared, and I certainly could NEVER choose this man over my daughter like your mother has. I am very sorry you have this kind of mother, you certainly did nothing to deserve that and I can't blame you for being angry. Given what your mother did, I don't think she is capable of caring no matter what is said to her.
