OK, and when she opens up and tells you all about it, don't argue, don't defend yourself, don't point out what she's overlooking... just listen and take notes and let her talk.
Right after my breakup, my WAW came back to pick up some things, and while here, we got into that conversation. I was totally open to hear whatever she had to say, and she opened up. She was never as communicative as she was on that day. I swear, as she spoke, light bulbs went on and I could see enough to connect all the dots for the first time.
