BUT do you understand the dynamics of the exact thing that turned HER around? Do you know when that moment came? Or do you actually believe it was his "hanging in there and not giving up" was what did it? (you are WRONG if you believe that)
It was when he told her AND showed her that he FINALLY understood that no matter what he did that he now realized that she did NOT want to stay married and would never love him again and that he was going to STOP trying to show her how sorry he was and he was going to stop trying to win her back....(and THEN he followed through on that)
THAT was HER turning point. It was when he told her he was giving up winning her back... She THEN wrote him the letter and then told him she wanted to try..
