In just my personal experience, I found that my XA would blame EVERYONE but himself for all of the woes of his life, UNLESS taking responsiblility for something meant that he could get what he wanted..... he would change his story.
Ex: He spoke so horribly about his ex. She was the reason of their failed relationship; she was evil, she drank too much and would yell...etc etc. Now this was when he was discussing a relationship with me. BUT when he didn't want me anymore and wanted her back, the failing of their relationship then became his fault. He abandonded her, etc etc.
See, after all of the bashing he did about her, he had to then change his story when he wanted her back.
In fact in relfection of all of his stories about his life and the problems he faced...I can't recall one problem that was his fault. Funny how that works.
