Welcome Bel,
through my own experience, I wrote a letter to N to express my feelings. Much like you I just wanted to have my say, even if in writing. N used the letter against me to show everyone how pitiful I was and that I cared so much more for him than he did for me. He also is able to banish people from his life as if they never existed. From this board I have learned NC is the only answer. It's hard, but this is not the normal person you can sit down and reason with or discuss your differences. I like you, saw it happen to others, but you just don't think it will happen to you. Guess what, it just did. Run and be grateful that you were let go with minimal damage.
