That is a question I have been asked by many, even early on as friends/aquaintences saw what she was doing and how she was treating me and wondered how I could want her back.
Truth is I love her. She is my soulmate. We have experienced so much (good and bad) together. I don't have the time to go over all the details. I decided early on it was not going to end like this. I believe this to be the challenge for which my entire life has prepared me. I committed myself.
