I must agree with Schrodingerscat.....again.
My wife and I have been in this situation. I sometimes feel that she is not moving forward, or at times, even trying to move forward. Then, when it all breaks down and disolves, she tells me that she was just on the edge of the precipice. I roll my eyes, and try to forget the whole previous relationship as it is painful, sometimes, to remember. The problem, is that in trying to forget, I also forget my mistakes. So.....Thank you for re-opening my eyes.
