My husband that I walked out on, wants me to explain to him how I have changed. I feel he is a manipulator, a damn good one because he is very intelligent, he obsesses about the truth and facts, throws them in my face continuously. He goes over the same facts about my mistakes in the marriage almost every day. These mistakes are his excuse for not letting me back to try and work it out. He is insistent on knowing how I have changed, he insists that I was cold and uncaring, and tells me he doesn't trust me because of past mistakes.
