Don't despair. In my experience people who don't seem to listen because it would mean admitting that what they believed is wrong, that somebody they relied on so much lied or distorted the truth, start the thinking process at some point. She won't be able to get your words out of her head, whether she wants it or not. It may take a long time, but I don't think she is indifferent. Otherwise she wouldn't have said that it was emotionally too difficult for her to stay in touch. The truth is very scary. She needs to find some courage to come back. Actually, I am in the same situation with the guy I talked about. In the past, I had also to deal with a guy who kicked me out of his office every time I told him what he didn't want to hear, which was basically every time. He didn't seem to listen a bit. I found out by chance that he had acted upon my advice several times ! I was amazed. Give it some time. Send a card for Christmas, Birthday as you probably do and after a while you can try to find out if her intentions have changed. What do you think ?
